My twin is bossy and loud. When we were about seven we talked about about being afraid of the dark, both saying we weren't. In order to 'prove it' we were to take it in turns to get into mum's wardrobe and the other would shut the door, just for a few seconds.
Being quieter I don't know how I managed to get her to go in first, however I shut the door, turned the handle. After about 10 seconds there was a little knock from inside, "You can let me out now," but no matter how I tried I just couldn't open the door. Whoops.
Mum had gone shopping (on foot, only three streets away) so I ran to find her. As she approached the front door I called, "Mum, help, R---- is stuck in the wardrobe!"
Her stunned reply, "Well, whatever is she doing in there?" She came up and freed her. Then of course R---- said, "Now it's your turn." "Not on your Nelly" I insisted. It was one of the few times I ever got my own back on her.
She's still bossy and loud but I answer her back now.
This little incident still makes me laugh.
