"Parents love their kids even when they mess up, huh?"
"I'm sure some parents don't, but they should. Love the person, not the behavior."
"Besides, everyone messes up. I made a mistake once that made my mother cry for two weeks."
"And here he is now."
[Chorus:]
And he said, "Let me tell you a secret about a father’s love,
A secret that my daddy said was just between us."
He said, "Daddies don’t just love their children every now and then.
It’s a love without end, amen, it’s a love without end, amen."
