I can't actually tell when I'm fake smiling or real smiling anymore.
I know that. My fake smiles mimic genuine smiles. I force the eye wrinkling so that my smiles look genuine. I've been doing that for forever. That's why I just can't tell them apart anymore. It's a trained reflex now.
that fake smile helps me humour people during my everyday life...do i use that more than my real smile?...actually i probably do
