Don't you cry

When I swore to never see you crying
I hoped we would not change until the end.
But as times go on, we have to live on
and nothing stays the way it was before.

As your tears are flowing like a river,
I break my oath, come to you, hold you tight.
When I can't be there to shield your heart,
I just have to make sure that it stays safe.

I want to hold you, feel you, want to kiss you,
but I know you can't endure the pain.
So I hide my tears and show a smile,
and stay as we are now until the end.

Let me be your pillow, when you're falling.
Just to let me see if everyting's alright.
Use me as you want until disposal.
But please promise that you'll never cry.
