Marcy and Franklin are in line for dinner together, trying to hear each other over the babble of other students.
"Not tonight, sorry," Marcy is saying, "I need to hide in my room garble garble my head feels like it's going to explode. How about tomorrow during work period?"
"I will plan on it. Do you want me to do the mathmatics in nature homework? This is me fishing for an excuse to do more math."
"You know what, sure, but don't forget that I owe you one."
