Dig this: You have a weird, bad social experience as a child, grow to understand it, move on, but still occasionally have the perpetrator pop into your world, and all that comes to mind when you see them is, 'Go away! You're not allowed to be within two miles of me! Didn'tcha read the contract?'
And you're not angry or hurt, just...you enjoy pretending the bully fell off of our flat, flat Earth.
