Keep on smiling

Keep on smiling
Keep on laughing
When you know
That I'm up here crying

Yet you don't feel an inch of guilt
While you know you've done this to me
Oh, but you don't know how I really feel
Deep down theres a truth to it.

But you'll never know it while I'm young
And so vulnerable to your senselessness
But trust me on this one thing dear
You'll find out someday.
