Why is it easy for guys to talk to other guys (and perhaps some girls) but suddenly such a challenge for guys to talk to a girl they seem to like?

There's a point to which I get it... you like someone and feel awkward and perhaps don't know what to say. Gals feel this way as well.

However I've seen guys who talk and are very charismatic with EVERYONE and then suddenly get to the gal they like and... I don't know. They clam up and become rude and act like they're suddenly not the smart competent person everyone knows them to be. Like a giant "brain fart" situation. I don't get it!
