I’ll block the toilet after having a wee with a whole roll of toilet paper-and then flush
ill put clean clothes back in the basket-or somewhere close to it
ill put the heating on full blast just before I go out
I’ll eat all the snacks in the house
i’ll break stuff-then deny ever coming into contact with it
I’ll wait until they ask if I’ll pop to the shop for butter/tea bags/yogurt and come back with a Diet Coke and a packet of crisps (which I’ll have scoffed on the way home)
bonus points if they really needed butter/tea bags/yogurt and I’ve just used the last of their money
ill leave all the lights on and go out
ill forget something and demand they bring it to me-now (even though I know they are at work and can’t leave)
I’ll leave wet towels under the bed-just long enough for them to go mouldy
I’ll appear holding an item of clothing that I need washing ‘right now’ and get all huffy and scream that ‘you’ve ruined my life’ when they explain they can’t wash and dry it in ten minutes-knowing full well I wanted to wear it a week ago but couldn’t be bothered to put it in the wash
