At least he did not throw a big party in your absence, which is already something to be grateful for.The problem is, 20-year old boy in my house makes a horrendous mess in my absence. I told him to feel free to use the house during the day for college study. He did. I can tell because of the huge pile of hemp bedding and chicken feathers under the stool he likes to sit at. And the same spread up and down along the carpet runner in the kitchen. And the splattered fermented feed all over the counters, sink, window and faucet.
