I'm not going to clean up my girlfriend's vomit
Why not help her out man?
I'm going to leave the vomit and I'm going to jump off a cliff
I know it can be gross to clean up someone else's vomit, but I don't think you should leave it, and you certainly shouldn't jump off a cliff. That would be going too far.
I'm taking care of her. We're not going to clean up.
I think cleaning it up would be the right thing to do. I think that you should try to just suck it up so it does not get more gross as time goes on.
