whts the most annoying thing someone could do on a first date

I would say talking on a cell phone. The whole purpose of going out on a first date is to get to know the other person. How can you accomplish that if the other person is jabbering on his/her cell phone during your date? I think the most polite thing to do would be to turn it off altogether, unless you're a doctor on call or have children at home.

I would have to say, I hate it when they talk about past relationships. This is very rude and very annoying. We are both here for a new start, now lets not talk about the ugly past. THANKS!
