"I was waiting for three hours for you to come back and remove your washing from the tumble dryer. As you didn't, I took it upon myself to remove them and carefully fold them into the basket that you see under this note. I hope everything is still here by the time you get back. Also, I wanked into your pillowcases. Love MadBob McCunt
