From First Grade To Graduation

I got on my school bus early in the morning,
It might have been different,
I arrived at the school and met my friends,
It might have been different,
I attended my first period class and started learning,
It might have been different,

Just like the usual I went to my other classes,
It might have been different,
At 2:30 the school was over and I went home,
It might have been different,
Just like the other days I reached my home,
But this time I knew it will be different.
