"I didn't think that it was gonna have to come down to that. Like, he was actually gonna go and take the sign and show it to people. And I don't want people to know that I, he's my dad. I don't want to be embarrassed by people," Destiny said.

"Never and in a million years did I think that that would be me. And I told my wife, 'This is America. And America is full of wonderful people. And I'm gonna go out and see what I can do and see if there's someone out there that can help us,'" he remembered.
