Prudie,

There's a guy I like a lot. We are friends. He is dating a girl who's living with another man. My friend says he likes me, too, but he wants to make his other relationship work. How can it work when she lives with another man? I want this guy really bad. He has a lot of good qualities. He and I have been alone twice, and the passion is starting to fly. I don't think he is being treated fairly by this other person. What should I do?

Dear D.,

For a start, you might try really hard to grow up. This guy you have your eye on sounds amenable to having a harem. Prudie also guesses his head is not on straight, what with trying to maintain a relationship with a woman who already has a live-in lover. Flying passion not withstanding, develop a hobby—quick!—and try to evaluate things with a more mature outlook. Reassure your hormones that another candidate will appear at a later date.

Dear Prudence,

Whenever one of those cars with amps, woofers, and speakers cranked up passes by going bang, bang, bang, etc., my whole body shutters. My heart pounds. Everything tightens up. Nausea begins. It is just horrible, like when someone has just scratched a chalkboard. Can you find any reason for this? Please help.
