...or just "Rain Man" variety autism? One of my friends has a weird quirk where every single bill he gets he has to pay in person, including those that are thousands of miles away. Yes, he's autistic (HFA) but I also suspect some OCD in there, too. While doing clinical hours at a "facility" (can't say more than that), I have seen some interesting behavior but this still takes the cake. Yeah it's weird when somebody has dementia and they think they are riding a horse which is a wheelchair or even think they are the horse but their diagnosis explains their behavior. But with my friend, there's nothing I have come across similar to this and he's also my friend so it's much more troubling to see weird stuff. It's one thing to pay electric and gas bill in same city or nearby cities, or pay dentist and doctor at time of visit, but to drive a few hundred miles to franchise tax board headquarters and east coast for taxes is a bit over the top. For some reason he doesn't "feel" people will get his money unless he personally hands it to them in cash or check. But he will never pay anything through the mail or online. If he can't get the time to make the trip, he defaults on the bill and it's as if he never had such a bill. If he doesn't pay a long distance bill, it's bad enough but when he drives, it's not always sober and anti-autism medication, whatever he has been given, makes him feel weird and doesn't do the same good as a few stiff drinks. That's something we have all seen to the detriment of many. This would be weird enough and could be chalked up to somebody who is careful about his money or his identity. You could see that he will never throw away plastic food wrappers if they don't have holes in them, and always wants to keep around any bottles or containers if they can at all be reused. His house smells worse than the local dump. OK, but he has a massive alcohol collecting hobby that is out of proportion with his income as well as a very costly day trading hobby/obsession. Though financial analysts can't crack the stock market on high risk trades, he continues to blow money there like a junkie. So saving money is not the major motivator here. The good part is that it doesn't affect anybody except his wife, but all this weird behavior causes a lot of personal stress. He could tell you that if somebody did what he did, he would call it impractical and stupid but he can't seem to control his own behavior. Just like the person smokes three packs of cigarettes a day yet knows it's bad and forbids his kids to smoke, this whole situation is a tough nut to crack.
