What do girls find boring in guys?

It really bores me when a guy that I'm trying to start a conversation with won't carry it on, and when there's no conversation going on they get angry. Or if they simply have a crappy personality.

well it really bugs me and makes me less interested when guys say I don't know or I don't care or whatever all the time. It makes them seem like they don't care and it just totally makes me look the other way.

A guy who has no interest or respect for the girl's friends or family. That is really annoying. I hate rude or brutish men -- somehow they think these manners are "manly". There not.

So...where do you wanna go. or so....what do you wanna talk about. just do something already!

When he has nothing to talk about or if he goes on as if he's only interested in talking all about him when it should be 50/50..and bragging about having a car etc...

When a guy constantly talks about himself non stop or like when he has absolutely nothing to say can bore and/or turn off a girl. hope I helped.
