"I've always been afraid to take risks."

"You're my best friend and I care about you."

"There's something I want to ask you."

"I'm going to go ask her."

"This is it. If I don't do it now, I'll regret it for the rest of my life."

"It's you that's not thinking fourth dimensionally."

"What if I can't get you back?"

"I've got to do something about these kids."

"I'll do anything to help you."
