My little sister (18) currently lives in my spare bedroom.
Generally she's ok to have around the house but she's either really helpful around the house or an absolute slob; depending on how she's feeling that week.
She left two weeks ago to spend the summer living at her friend's uni house at the other side of the country. Before she left she was under strict instructions to clean, tidy up and change the bedsheets. She managed to hoover the carpet by lifting the pizza boxes onto the bed and then back onto the floor. The sheets were changed the night before she left but she got make up all over them. There's probably half the kitchen up there probably growing a new variant. I could never have any guests up there as she literally pushed everything to the side with everything she decided not to take on the floor!
AIBU just to close the door and give her quite a shock when she gets home? She is coming home to visit for the weekend in a couple of weeks but I very much doubt she'll be wanting to spend one of those two days cleaning her room?
Is it also bad that anything she's left thrown across the house has now been thrown onto her bed/floor?
