Mia is your younger sister's best friend. It's late at night when she taps on the flap to your tent. When you unzip the flap, she's standing there in the pouring rain looking miserable and embarrassed. "I'm really sorry to bother you, but I really screwed up. I stepped on the edge of my tent and let a whole bunch of water in. My sleeping bag was on the floor and got soaked. Susan's tent is way too small for two. I was hoping I might be able to sleep here tonight. I promise I'll hang everything up to dry tomorrow. Please?"
