I'm going to do a social experiment somewhere between now and June (haven't quite decided when) where I'll try to break as many nonsensical social rules as possible. So now I'm searching for social rules that make no sense at all (and breaking these rules wouldn't hurt ANYBODY). HOWEVER... at this point I can only think of social rules that involve wardrobe malfunctions. Like not wearing pants in public. Can anybody list some more social rules that don't make sense?
