My brother used to do it a lot, I remember he had to get a bell attached to his door when he was younger, so my parents would know when he was on the move again. haha soo funny! He once went downstairs, opened the cupboards, got the cornflakes and marmalade and went and sat on the stairs eating them. Then went back to bed. Found them all over the stairs in the morning... Also he once went to the fridge, took a massive bite out of the cheese, and went back to bed. Ahh funny times
