Dear A. - I am writing to express my gratitude for your gift. There are no sufficient words, but please accept my sincerest thank you. Yours, R. She writes me back. I didn't expect that. She tells me she's a lover of chicken pizza and video games, a hot sorority girl with the nickname Sloth. She wants to know something about me in return. She says I owe her. This is how she saves my life. She doesn't even know it. We've never even seen each other...
