For an actor, for me, I love being able to tap into just heavy emotions. I don't need to be balling in every scene, but I just love to feel different emotions when heading to set. It's a lot of fun to play with.
In marriage people get in fights because they don't communicate, because you don't want to hurt the other person. If you do want to hurt the other person, then shame on you - you're an asshole. My wife and I do not argue. We communicate. We talk. But we've never fought in our entire relationship.
There's the really angry drunk, who's just annoying to be around. I prefer the drunk who falls all over the place and is being completely inappropriate. Or the super-loud, happy drunk, which is evidentially what I am.
