There's a TV show called 'My Strange Addiction', it documents real people who have strange compulsions or behaviors. Some of the topics include people who eat nail polish, dryer sheets, detergent, rocks and dirt, a guy who dates his car, people who are adult babies, and so on. One guy on the show loved to pull hair out of drains. I was like...so what?? I couldn't understand what the problem was. He admits his habit to his friend, whose drain he secretly pulls hair out of when he comes over. Then they start talking about getting him some 'help' for his 'problem'. Really??
All of the other topics on the show were harmful in one way or another to the person doing it and/or their loved ones and I can easily see why they needed help. I don't see how this particular guy needed help. I've pulled hair out of drains myself because I have long hair and it's something that I just have to do every so often, and honestly it's pretty fun and satisfying. I don't go around doing it to other people's drains, but even if I did, what the hell's wrong with that?

I don't like it when people think that unusual and problem are synonyms.
I shall return to detail my attempts and describe the fruit of my labor!!
If I'm not back in 15 minutes, just wait longer!!
Why would you do this to me?
I wouldn't mind if someone pulled hair out of my drain, he'd be saving me the effort of having to do it myself.
I can't see how an obsession for any form cleaning can be a bad thing, unless someone is scrubbing their hands raw. (or if you're this person >> http://isitnormal.com/story/i-only-take-baths-with-bleach-and-ammoinia-37162/)
I wouldn't mind him coming into my house and pulling the hair out of my drain. It's a win win. :D
