I know how to explain why it snows and I know how to explain where it happens and how.

I know how to explain why it hurts when you have a fight, when you cut your finger with a knife or when you fall to the floor.

I know how to explain why the atom is the smallest unity of an  element.

I know a lot of things.

But...

I don't know why it hurts when you don't look back.

I don't  know why sometimes it ain't supposed to be happy....even eating chocolate... or listening Smashmouth... or watching a comedy or being with friends.

I don't know why or how... but it hurts a lot when you're not here.

:/
