If you can come up with the money tonight, I'll bring the bike and the truck over there.. sell you the bike.. and help you haul all your stuff away in the truck.

Seriously though.... the story is really still not very clear. You and your sister got into an argument, your mom and dad are pissed.. and your mom doesn't want you to leave the house. I grasp that part, but there's got to be more to the story. So, calm down, breathe, and tell the story.
