They

There are time when we feel like there's no one there for us.
We don't notice the poeple who want to be there because we're too caught up in ourselves.
They sit and wait for us to realize that they will always be there,
But we never do see.

That's when those who have been waiting so long start to disappear.
They move on with their lives while we continue not to notice.
They simply give up on us, but it's not their fault
Because we never do see.
