I try not to comment unless I have something to say; I will sometimes post "I agree!" or "hug!" type comments but more often I write them, stare at them a bit, and back out of the posting page.
I agree with most of the political stuff you post, but I have a tough time engaging too much because I just feel sick after a while. I either feel bad for not keeping up enough with politics or feel worse for knowing what's going on and what elected officials are saying and doing. =/ I've known I get like this since I first decided "I will keep up with politics!!!" when I was eleven or twelve, and I still haven't figured out how to deal with it.

I would love to actually watch a football game live, but I can't get into sports unless I'm physically at the game. It doesn't work for me any other way - and some sports, like US football, never interest me at all.
