[Heera Rajan]

im in 8th grade and theres this guy in school(also in 8th but in a different division).....he sent me a facebook friend request and i accpeted after which we chatted and became friends (it was during our xmas holidays)...after school reopening we met eachother in person and he was looking at me in a..a.....a 'flirty' way. i didnt react to it that much back then but for the next few days-
*he was looking at me...
*he came to 'talk with his friends' INFRONT OF MY CLASS every recess..
*he comes to talk to me but for silly stuff that no one would like to use to 'break the ice'
*he chats with me on facebook
..i was certain that he has a crush on me but for the NEXT few days he...
#looks at me for a fraction of a second but IMMEDIATELY turns his head when i look back....
#doesnt say hello or notice me like he did before
#doesnt chat with me on facebook unless i say something...
i first didnt notice him much since he keeps looking at me but now i try to notice him better than before but now hes the one ignoring me but HIS FRIEND stares at me like a vulture while he keeps his head at a different direction...
WHATS WRONG WITH THIS GUY!.............AND HIS FRIEND ALSO!!!!!!!!!!!????
