when you're trying to fall asleep and you suddenly remember something stupid you said to someone years ago

You're lying there at 11:47 PM, finally warm, finally comfortable, and your brain decides to play a highlight reel of the time you said "you too" when someone told you happy birthday in 2016. Your body goes rigid. You're now 100% awake and furious at a past version of yourself who can't defend themselves. You spend the next twenty minutes constructing elaborate apologies to someone who definitely doesn't remember this happened, then realize you're never sleeping again and check your phone: 11:52 PM.
