Little crush or desperation?

Once in your teenage life you have that little crush. Although in my opinion my crushing time has already passed about 2 years ago. Thats right, i didnt like anyone at all for 2 years. For a teenage girl it might be quite strange or not but Im not sure to be fair, it depends on the person I guess.Is it strange that I like someone who I didnt really speak to before? Maybe it is.  Anyway, I think I might be crushing on someone. I dont know when or how this happened but there is a guy in sixth form (year older than me) that I never really noticed before but now when I look at him I see a potential crush. Is it strange that I like someone who I didnt really speak to before? Maybe it is. Maybe I'm just really desperate since i didnt like anyone for a while.  He is good looking, plus he's geeky and I really find geeks cute. I never really had the chance to speak to him and also I didnt have him on facebook until yesterday. Haha yea, I kind of found out what his name was and did a little research and then added him on facebook. He accepted my request and also liked my profile picture haha which i found quite strange but sweet. So today I went to school and I just randomly walked around with my friends and then he walked past me and we kind of smiled at eachother. I dont know whether he was smiling at me or at himself randomly but I dont know. I might be just thinking bullshit. So I decided to see on his fb page if he has ask.fm so I could ask him some questions and maybe make friends first online or kik or anything so I wouldnt have to say who I was. Im really shy you see so I just wont talk to him like that because he will look at me strangely but I will do something, Im not sure what yet but Im open for any suggestions -.-
