"R u ok?" Is a way of giving the illusion that they care for image sake...and you know they are hoping the answer is going to be "yes" because like they are really wanting to know, unless they are a medical professional. When you actually say "no,...." ....they look at you like they wished that they have never uttered them words....so to appease their ego, I say "yes".

I think my new answer is going to be "you have no idea, c-ya"
