Mean buyers

The buyer put a contract on our house, then had to store all their stuff in our attic, then settlement was delayed by a year so their stuff was up there forever, then they had a pre-settlement walk-thru and the agent demanded I make them lunch. I hardly had any food in the fridge but I attempted to make some food and they ended up not eating any of it. Then, while I was slaving in the kitchen, their kids were drawing on the walls with crayons.
