I read a book called THE Mess.
A boy's room was very messy, so he had been told "Clean a room!" by his mum. Then the cupboard was empty, so he put all his things in it. But when he tried to get the broom out of it, all what he had put in it, fell down! That was NOT a good idea...
My room is so messy, too. So I can understand why he did that, and if I were him, I would do the same thing...
