Two of my DC managed in their turn to lock one of their siblings in a room when off to school (probably accidentally ). One had to ring me to dash home from work (after failing to climb through a window) as they’d set the house alarm off, the other escaped by kicking out a panel in the door, Wonder Woman style.
Neither escape as dramatic as DH’s when he was in his teens and locked in. He went down in the cellar and tried to squeeze through the coal hole, got stuck halfway, and had to call weakly for help till a passing pedestrian hauled him out. Oh, how I wish I could have been there!
