Once some guy mentioned that when i laugh my mouth looks really weird and now whenever i laugh around people i don’t know 100% i cover my lower face with my hands.
A girl who didn’t like one of my friends told her that her eyes squint different sizes when she smiles, and now whenever she’s happy she look’s down or away.
You’ve gotta be careful with what you say to people, because it might turn their happiness into insecurities.
