What not to do on a plane to your fellow passengers

[Undertoad]

When I was 18, I saw a short piece on schizophrenia where this schizophrenic guy couldn't put his left arm down. It was stuck. When at home he would mask it by reclining and putting his other arm up, like he was relaxing. But he would go out and mow the lawn, and his one arm would be up.

Well this freaked me right the fuck out. From then on I started to worry every time I put my arm up - is it gonna just stay there, because I'm mentally ill, and that's it for life, now?

Which is stupid, because that's much better than, say, being blind or deaf or something, just having your one arm up all the time. But it's the embarrassment, you know? If you're blind, people don't want your story, they just want to pet your dog.
