That parrot story is wild and I can totally see how it messed with your head. My cousin does HVAC in Kansas City and got called to a house where the owner had this ancient cockatoo that screamed "GET OUT" every time the furnace kicked on. The owner just laughed and said it learned it from her late husband who hated the cold (which is kind of funny but also super creepy when you're alone in a basement). The worst part was the bird would only do it when the owner left the room, so my cousin looked insane trying to explain why he ran upstairs. Pets pick up the strangest stuff from people and then just repeat it at the worst possible time with zero context. At least your parrot had manners, even if the timing was terrible.
