The first thing came on Monday night, while I was finishing up my homework and Zoe was working on her homework on her computer ... or, at least, I tho...ght that was what she was doing."YES! I'm in."

Sorry, go back to your book."She has a terrible poker face and I was instantly intrigued, so I set my school books down."Nuh-uh. I don't buy that. What are you doing over there?" Well, I was talking.
