Question: Why are men so "clueless" sometimes?
Answer: Men seem clueless at times because we are. Most of the time when you ask what we're thinking and we answer nothing, generally it's true. Most of the time we're really not thinking about anything. Most guys like directness - if you're feeling mad, upset, don't like a movie, concert just tell us. Better to do that than send signals that guys don't pick up on anyway.
I'm sure you've been at a bar or party and there is a guy you like. Instead of flirting across the room simply go up to him and strike up a conversation. Most guys would welcome that. That's happened to a friend of mine while playing volleyball - she liked this one guy or at least thought he was hot without his shirt on. So me being the helpful guy trying to get my female friends laid told her to simply go up to him and strike up a conversation. On a side note - beach volleyball is the place for single people (guys and gals). The women are in bikinis and the guys play shirtless. But she never did go up to him, I just couldn't understand it. Not sure what my point is, but I hope I answered your question.
