You say I've done a lot of good
You're glad I found you when I did
But I wonder why you keep
Those questions in your head
Oh I think you're afraid to fall
Someone went and blew the call
All I can say is my heart tries hard
Try as hard as I can
You'll never find that my love falls short
One day you'll understand
That I've got a heart that can
Well I think I know by now
I will be standin' by your side
Takin' in account true love's never shy
I can show you everyday
This is not a one act play
All I can say is my heart tries hard
Try as hard as I can
You'll never find that my love falls short
One day you'll understand
That I've got a heart that can
So let me love you the best
That I know how
Let me move you with
Everything that love allows
All I can say is my heart tries hard
Try as hard as I can
You'll never find that my love falls short
One day you'll understand
That I've got a heart that can
