I had this happen to me a few years ago but it was my hubby and a granddaughter that lived with us. We had moved into a much smaller place so my STUFF whether it was sreing, crafts or just stuff was stored everywhere and they were always complaining so I got mad and had a yard sale. Of course all I did was cut off my nose to spite my face as the old saying goes. I have not let them forget it either. Everytime one of them said anything after that I told them that just as soon as they get out their stuff for a sale or giveaway then I will get mine out. Seems to work.
