I think that a lot of things can be comforted with a hug.
We don't need no drugs, alcohol, food binges, shopping sprees, or one night stands.
We really don't.
It's like there's a little kid in me that, when hurt or disappointed, just looks up and asks for a hug. I'm pretty sure there's one in everyone too?
Maybe that's why I want a dog. (They're so fluffy! Fluffy hugs!! Also they love being petted and probably will tolerate random unexplained hugs heh heh.)
