Look at how the animal's own behavior can ruin your best plans. My friend's dog once bolted because a squirrel ran past right as she was opening the car door. Your parrot probably saw something amazing outside and just went for it in a split second. That instinct is stronger than any training in that moment. It shows our safety steps have to account for the creature's wild brain too, not just our own memory. Makes you wonder what tiny outside thing caught your bird's eye, right?

Yeah, totally get that. @hannah926 is right about avoiding drama, but this would eat at me too. Maybe just ask her if she has a twin.
