Isn't it generally understood that when you hang out with someone or go on a "date" with someone that you shouldn't start having long cell phone conversations in the middle of it? When did such interruptions become polite? Those nextel 2 way things are the worst -- you have to hear both sides of the impolite conversation. It wouldn't be a big deal if it was a short conversation or just saying "I'm busy. call ya later", but after a while, it's just not cool. Come on now; I'm not being unfair.
Maybe I'm just old fashioned or something, but I thought it was considered a good idea to pay attention to your date. Then again, I'm not hip to culture these days. Apparently, "rude" is the new "polite".
