Dude, I was going to start a similar topic the other night. I noticed that some peoples (ESPECIALLY college age and younger) conversations doesn't go beyond sports, make-up, clothes, and who's dating who.
Like someone said, there needs to be a balance. While I like to talk about sports, sex, parties, clothes, gossip, etc. I also like to talk about current events, religion, and even little about philosophy, science, and politics. Hell, I just like to talk, even occassionally when I don't know what the hell I'm talking about.
Sometimes I wonder about really superficial or really deep people.
