A thought?

When you look at me
I always feel shy
and I don't know why
I'm afraid to melt,
drowning with your sweetest smile
And that would always be in my mind
Even though I act as totally blind
I'm afraid to see you
Knowing that the past willn't be back forever more
and It hurts even more
I wanna be happy, but I can't
For, it seems like somebody is missing
and I guess, its you.
