Ha ha that's what mine does too, she's always in mine, like you said I can't open the door to get in there, no gaps in the floor-drobe at all, totally mingingYep and I bet my daughters will be as well but that doesn't make me feel much better lol! I tried to take some clean stuff in there yesterday and actually couldn't open the door without difficulty!
She is very busy at the mo and working various shifts and I don't have to go in there very often but why its starting to bug me is she is now using my mirror and the other day had been in my room on my bed to watch tv...probably cos its so disgusting in her room she can't get to the bloody mirror!
