Emtpy is only empty, because you see it that way. Forget about perceived emptiness and move on with your day.

But God has also given us the power to forget, so that when the tragedy is over we carry on as normal.

Well, now
If little by little you stop loving me
I shall stop loving you
Little by little
If suddenly you forget me
Do not look for me
For I shall already have forgotten you

If you think it long and mad the wind of banners that passes through my life
And you decide to leave me at the shore of the heart where I have roots
Remember
That on that day, at that hour, I shall lift my arms
And my roots will set off to seek another land

Days will have to drag on longer, but eventually I will stop thinking about you.

You can't look back - you just have to put the past behind you, and find something better in your future.

It happens to everyone as they grow up. You find out who you are and what you want, and then you realize that people you've known forever don't see things the way you do. So you keep the wonderful memories, but find yourself moving on.
