The fact that when people tell you they want to give you a lift or help you out in some way, they actually seem to mean it. I come from a culture when you offer to do something for someone (say, pick up a package at the post office) not only out of the goodness of your heart, but for a whole host of other reasons - they're older than you, they outrank you, etc. So when I would say, "Oh, it's no problem" to offers, because I'm expected to, in case they want to opt out, I was genuinely shocked when people said, "If I didn't want to, I wouldn't have offered." Wow. I liked the sincerity!
If we are that concerned we will ban motorcycles and while we are at it, cars. Just think of all the injuries and fatalities that would be eliminated. We'll all sit at home and watch ball room dancing on TV. Can't be too safe can we? [end of sarcastic former New Yorker response]
