I'll never understand why people like pointing out someone's emotions.... like if someone is looking sad or something or deep in thought....let them be that way in peace.  Like you aren't being some hero by running up to someone who obviously doesn't want to be disturbed and then going "you look sad today".  Like stfu.  what do you gain from saying that?  Do you not have an inner monologue?  Living life on autopilot?  You just need to narrate your observations out loud? stfu.
