No joke, I have a very close friend who is a vagabond. It the most literal sense of the word. He has no permanent residence.

I love the guy, he's a great friend, loyal, dependable, trustworthy.

But, I've heard that people have found objects beneath the couch he crashed on with... certain matter on it.

Hey, I'm not judging, but at least you could take that with you, or wash it off.
