Yo Kass answered Could it be a smile?It seems to tick all the boxes...You don't technically own your smile (although try telling your dentist that when you get a dental bill).You can give anyone a smile, it's pretty easy. Even people you really hate can get a sarcastic smile...And you can give it away as many times as you like, without losing it. Just ask this guy, he's been dishing them out all day...
