I Like Intelligent Conversation

I'm not trying to sound high-profile here but I really like having a conversation that actually makes sense and makes me think a little. Th best part, I get to learn something and feel enlightened.
I'm not amused by 'LOL' at all.
Maybe because I'm not one for dumb talks that I don't give much reaction to people trying to be funny and they all say that I look serious. Most of the time, I just raise my brow and show a 'Are you serious?' face.
But of course, don't make me feel absolutely stupid by putting really intelligent people around me, I'd feel really stupid and left out.
