I have luckily never done that but my ex did it all the time, he'd leave his keys in the lock outside the door. I took them out one day and hid them for days. Before he was to go and try to get new keys for his car and the doors, I dropped then near the sofa so he thought he'd done it. Thats the last time now for a month he's left them in the door. I think it taught him a lesson, and theres no excuse because he isn't trying to balance a child, packages etc., its just his stupid self...
