Quote by Marty McFly

"This is heavy."

"There's that word again, 'heavy.' Is there something wrong with the Earth's gravitational pull?"

"I'm your density. I mean, your destiny."

"You're my best friend, and I care about you, but don't ask me to do this."

"Time waits for no one."

"Time spent with loved ones is never wasted."

"I've been alive for a long time. Long enough to know that you can't trust anyone."

"The past always catches up with you."
