I've just been messaging my lovely DIL and we were chatting about the things we have done when we have finally lost patience with people we house share with.
When I was in my early twenties I shared with two male friends who never lifted a finger to clean anything and one day, after walking into the kitchen for the umpteenth time and finding not one clean piece of cutlery or plate and every surface of the kitchen covered in gross dirty crockery and pans (I had been "on strike" for days and not cleaned up after them) I proceeded to throw the lot out of the kitchen window onto the courtyard below for them to find when they got home. So satisfying at the time but now I'm a little bit mortified that I did it, wouldn't dream of doing that now (I've matured!)
DDIL had a similar story about a house share she left. What's the worst, passive aggressive thing you ever did to get the message across to you fellow house sharers?
