When a girl you've seen several times but hasn't really waved at you and doesn't really notice you, or know you but has seen you before.. and then a (bit new) guy comes and then a week later (i don't know what happened or how), the girl sees him behind her and waves at her.. what would it mean?
Make a list.
- She might've known him before.
