when we were teen

Is it possible to fall in love with someone after knowing for 12 years....we were classmates for 10 years .....It started After my grade 10 exams I joined tution where my bestfriend goes and surprisingly he goes there to.....On my first day of tution ,he was absent so it was natural that I didn't know he also comes here......on my second day he came 30 minutes late, I thought just like me he was also new here but who could have known that this tution classes were about to bring a big change in my life He was 2 years older than me, because I skipped grades in my childhood and yes I was a good student when I was kid but academic and adolescents have make me a average student.....He was a popular guy and he talk to practically every one in our class....He was good looking handsome and was 6 feet tall,he has a great personality he can instantly light up the environment that's why he was everyone's favourite when did you find out you love someone... for me it was probably when I started caring for my looks,how I dress which dress makes me look good or maybe it started when I looked forward for tution classes.....The fact that I have a crush on him,I hid it from my friends probably because I was too shy to tell them ... everyone at the tutions were allotted a fixed seat and he sits just opposite to me .....you may say it such a good chance to see your crush ....it was a good chance only if I have the courage to look into his eyes ,but I was too coward to meet his eyes ......there was a day which I will never forget,one day he didn't bring his book ,so I lent mine ,I can't tell you how I felt when I saw him holding my book it was unforgettable In my 11 grade exam .....he sat beside my seat and it gave me so much butterflies I was literally feeling that I am a garden rather than a human.....but every one sided love have more cons than pros .....we both choose different path for our future's .....I knew sooner or later we were going to be parted so rather than focusing on the negative side I thought to spend the last year's of my high school peacefuly
