"No. I'm fine. I can carry it."
"Come on, you know you're back's gonna hurt in like five minutes. We still have a long way to walk."

"I. Do not. Need. Your. Help!"
"You're panting. You couldn't be in more need. Just give it to me, I won't be a jerk about it anymore if that's what you're worried about."

A dust of hands, a hidden grin and a quiet whisper. "Works every time."
