Empty spaces

I dont know my best friend anymore
He sits beside me on the bus going home
He looks like my best friend
I think hes my best friend
He WAS my best friend
Its like we dont know each other anymore

We once said nothing would ever come between us
But now there is
Nothing
Nothing at all between us
We talk every once in a while
but there is this empty space inside me
where he had once been

We are both changing
We are going our seperate ways
We are making new friends
Meeting new people
Just plain out changing,
Sometimes it feels like there never was an us,
Not even a we
