Q. I Found Pictures of My Mom on Our Computer: I'm 15, and several years ago I was searching all of the digital pictures on our family computer, looking for something for a school project. What I found instead shocked me; it was a picture of my mother wearing sexy lingerie in our living room. The first thing you should know about my parents is that they are not in love, which they have told me many times over my life. They put up with one another "for me." Back around the time I found this picture, things were already very tense between them, and arguing went on all the time. So my 10-year-old self decided not to show her. But I haven't been able to forget about it and recently a whole new thought came to mind; why did my father have to take a picture? My mom clearly does not know this picture was taken as she was looking at something else in it. I'm worried that my dad may have e-mailed it to someone or possibly posted it on a Web site after one of their fights. My mom and I have the most honest relationship you can imagine, and I feel like I'm hiding something from her by not telling. But things have also gotten better with them since that time, and I don't want to ruin it now by bringing up the past. What should I do?

A: Before the Internet, children used to rely on their parents' dresser drawers to find out things they shouldn't know about them. My parents used to keep their dirty books hidden under the bed, and when they were out, my siblings and I used to fight over who got to the stash first. And keep in mind, before the modern house was invented, the entire family lived together in a cave or teepee or yurt, so imagine what children learned about their parents' love lives.

Your mother probably knew your father was taking a sexy picture of her, and I very much doubt it has gone viral on the Internet. Despite their miserable marriage, it's actually nice to know that they have an adult connection. So just forget about this, until you have a teenage child of your own who you can tell this story to. What's actually disturbing is the fact that your parents have put the burden of their unhappy marriage on you. That is a gross violation, and I hope you have some reliable adults in your life you can talk about this with.

Q. Roasted at My Wedding? My fiance and his friends have a tradition of doing roasts at major events—weddings, milestone birthdays, etc. They have an open microphone, and basically anyone can get up and give a speech that teases the guest(s) of honor. I think you see where this is going. ... My fiance wants our friends to roast us during the meal at our reception! Honestly, the idea makes me feel like I'm going to throw up. For one thing, I think weddings that are too heavy on speeches are a bad idea, because no matter how funny the speakers are, there's a point where people glaze over. Moreover, call me Bridezilla, but I just plain don't want people to make fun of me at my wedding! I find the idea completely mortifying. I was thinking a toast or two, then everyone enjoys their meal and catches up with their dining companions. I suggested we save the roast for the rehearsal, since it will be a smaller group of people who know both of us very well. However, my fiance is in love with the idea of a reception roast, and once he gets really enthusiastic about something, he gets carried away. My hope is that he'll come to his senses sooner rather than later. I'm willing to put my foot down and go bridezilla if I have to, but I'm hoping there's a better way.

A: The only roast that belongs at the wedding should be in the form of beef. You are not going bridezilla, you are trying to make a very reasonable distinction between your wedding day and a show on Comedy Central. Opening up the event to a roast not only, as you say, promises to make the evening a giant bore, it invites friends who've had one glass of champagne too many to reflect on what they know about the sex lives of the bride or groom.

Maybe you can tell him that you hate the idea, and since he's so committed to it, you'd like to discuss it with a few close friends. (Pick people who have good sense!) Maybe this intervention will help him see this would get your marriage off to a bad start. And if he gets all groomzilla about this, maybe you two need a mediator before you tie the knot.

Q. Potential Party Pooper: I've been dating an ex-co worker for a year. We decided to live together. We are in the midst of planning our first party together, and he wants to invite his boss. All well and good, except his boss was my boss who fired me. What do we do? This is a very small company, and I'm sure his boss will find out about our party. I'm concerned about the possibility for backlash if he isn't invited.

A: When Winston Churchill was turned out of office, his wife remarked that it might be a blessing in disguise. He replied, "Then it's very well-disguised." But it sounds as if your firing, painful though it may have been, ultimately has been good for your relationship. (It would be difficult if one of you was employed happily, and the other very unhappily at the same place.) Your party is a great opportunity to smooth things over vis a vis you, your boyfriend, and your former boss. Of course the boss is going to hear that you two are living together, and he's probably worried this might cause friction between him and your boyfriend. So invite the boss, welcome him with a big smile, and say something about how it's nice you two can enjoy each other's company in a purely social setting.

Q. Visiting Boyfriend's Family for the First Time: I am in my mid-20s and have been dating a wonderful man for a while now. I will be visiting his family for the first time in a few weeks over a long weekend. What should I do/not do to ensure that I make a good first impression as a house guest? What would be an appropriate plane-travel-friendly gift to bring? Also, I have a special diet, and I don't want this to be a burden to his family. Do I bring my own food along or make a quick stop at the grocery? Or do I ask my boyfriend to communicate this and just hope for the best? Any advice would be greatly appreciated!
