It's like the "smile". The smile that I see on faces when I walk around - I mean the faces that I have never seen before and will never see again.

It's just pulling your corners of the lip away from the middle and just nod mindlessly which often actually looks more of a frown than a smile but that's called the polite mandatory smile. Nobody who has ever smiled in their lives or have seen someone really smile takes those smiles as smiles at face value, do they?
