thank you sir you are very kind

One of the things the doctors tell me a lot is "Well, that's what happens when you get hit by a car." Oh, really? Wonderful. I thought it wasn't. But it seems so... purposeless. Yes, I understand that, given the car, this is natural. But why the car in the first place? That's the questioniola. Is getting hit by a car "what happens when you live normally"? I don't think so! This is a really weird way of encouraging someone.

"We-e-ell, don't you worry! This is what happens when you get hit by a car."
"Thank you, sir, you are very kind."
