parent sex.
LevYou know what's worse than hearing your parents have sex?
Almost hearing your parents maybe having sex. Because, then, every innocous sound becomes something terrible that hides in the night. And you're laying there thinking 'Well, maybe they aren't...but if they aren't and I think they are, how terrible does that make me'?
It's like how a balltap can be worse than a straight up punch to the nads
but instead of intense testicle pain it's kind of an enduring sadness that you had to be there
