There's nothing that really annoys me about guys, specifically. There are a lot of stereotypical "guy things" that I find myself noticing in girls, as well.

i think it would be the lack of ability to mind read...lol

When he tells me things and expects me to rmemeber them forever till I die

Having to be right

I'd go with the stereotypical saying one thing and meaning another.

Her shutting down and not dealing with things. but I understand it

Unfaithful.

The lack of ability to understand the other gender...

I believe most females are not honest with themselves about what they truly want, regardless of what that is. They are willing to tell everyone but their spouse about the deepest, darkest feelings but the spouse is left to guess. If a woman cannot be honest with herself, she cannot be honest with anyone else.

Sticking to an opinion when all evidence is to the contrary.

Not saying what they mean. For crying out loud ladies, stop using code!

Not much

chicekn cluckers... have stand there and say the same thing over and over..

I don't spend that much time thinking about the opposite gender. I'm gay, so... it's kind of moot...

Judgment, impatience, lack of tact and needing to flirt constantly.
