*Should I add him on facebook?*?

[818]

So I like this guy in one of my classes, hes one year older than i am, and we're in high school. ! I've liked him since the beginning of the school year, and i actually first noticed him because i saw him glance at me a few times and everywhere i turned, he was right there. We don't really talk though, I'm so shy around him, I feel my face start to burn whenever i even see him looking at me. We sit across the room from each other, and sometimes when i look at him, he'll stare at me for a while until i look away from shyness. Just the other day, him and his friend were both staring at me for literally like 4 seconds. Also, recently, i was going to class and he was coming the opposite way i was and once he saw me he turned around and followed me! (I know it sounds weird but it was cutee.) Another thing is about a day ago, i was walking past his table and his friend (the same one i mentioned before) said his name kinda teasingly. My friends think i should friend my crush on fb but i don't know if he even likes me? Opinions please!!!?? Thanks so much everyone! )
