What would you do if a girl smiled at you in the halls?
Soo just smiling most likely ismt enough but its a start. I really appreciate and notice a woman that likes to smile it tells me she is happy with herself and who she is. Try approaching him and... Flirting
If a guy has lots of girl liking and commenting on his social media, does that mean he’s secretly flirting with them all?
Soo I would say that he is most likely flirting with a few but definitely not all Flirting
His he being friendly or is there some attraction?
When a guy takes time out of his day to notice and be noticed by a woman he is definitely interested. You should talk to him on a more personal level meaning ask him thoughtful questions and... Flirting
