I need help lovely people :(?

[203]

so I'm a junior in high school and there's this kid but he's a sophomore. I think me liking him is really wired because I'm a girl and I'm older but I don't think he likes me back. we're complete strangers , I know his name and I know he has a Facebook but il afraid to add him as a friend. It all started when my friend and I were leaving to lunch and he was infront of us , he turned around twice and looked at me. After that I was walking to class with my friend and he looked at me for atleast 3 seconds. After that , the next day he was talking to his friends but he turned around to look again. today he came up the stairs and I looked up to seer him looking at me. when I started walking behind him he turned around again. when I was leaving school with my friend , he was talking to some girl , I turned around to say something to my friend and my other friend said that he looked at me. does this mean anything , does he like me ? what should I do ? dirty for the long and boring details
