Things are starting to run in and out of my mind since I started thinking of her.
I've felt this way before, I've felt it many times actually, All in the last minute, Because when I feel this feeling, Next day you'll know is they have a boyfriend, they'll be moving out, I cant see them again because its graduation, things like that..

(But now..)

All this is because of my cowardness, my shyness, not having the courage..

(Now, Maybe now..)

But is this the right thing?

(Yes, Now.. Now will definitely..)

No, its not, its not the time, I still have things to do, things to prove, I still have to make them happy

(But am I happy? I want her.. I want her bad..)

But do I have a choice?..

(Do I?..)
