Its Been Awhile

So im in highschool and last semester he sat by me in 2 of my classes. And we talked a little bit. I started liking him in october. I dont even know how it started. Hes really cute, nice, funny, smart. Sometimes he looks at me alot which makes me think that he knows but then other times he doesnt do that. We hang out with completely different people. I try to send hints but not too obvious because i want him to think that i like him but not actually know it so i dont embarrass myself. But i really really like him so ya.
