Bumpers aren't really for bumping.

I bumped my car into a coworker's car trying to parallel park in a too-small spot last week. Aside from feeling like a right nitwit, now when I'm coming to or going from work and don't see her car, I can't help thinking her husband (with whom she commutes) decided to park their car elsewhere that day. "She can't hit it if she can't find it!" he assures himself.
