I'm beginning to think that it IS a trick question. That, however, wasn't my intent.
Because the NEXT thing someone said, right after I posted this, is that "the clothes were NOT on the carpet, they were in a neat [HA!] pile in front of the door and why can't I stop telling tales."
Amstaffer (your name's Dan, right?) my dad was out in the woods all day, and my mom is highly allergic to poison ivy - he is not. He goes in places that have it, and she has asked him to strip at the door and put the clothes in the washing machine, but instead he left them on the living room floor, on the freshly vacuumed carpet (leaves, sticks, and dirt, anyone?) and I mentioned it to her when she called, and when she came home, she asked him about it - stupid, but whatever - and he immediately told her I was lying.
