Come to think of it, before my ex moved out, my neighbors probably hated me, too. We'd have awful fights, screaming matches, swearing, he'd hit me and I'd hit the wall...anyway, we had a fight one night and I said something about what he'd done to me in the past (long story), not realizing that someone was standing right outside. I wasn't sorry for what I'd said to my ex, but the next morning, I caught up with that neighbor and I apologized for him having to hear it. He claimed he didn't really hear anything, but then he said, "Little argument, huh? Don't worry, I've done it, too."
I still feel bad when I think about that.
