"No, really," Marshall said, balancing his phone between ear and shoulder as he measured sugar into his mixing bowl. "I'm baking. Like, the common room on each floor has pretty much a full kitchen, it's totally cool."
"I didn't mean that," Corrine said, on the other end of the call. "I was surprised that you're baking, not that there's a place at your school you can do it. Since when do you bake?"
His timer dinged; Marshall turned around and pulled a pan of
orange-flavoured cupcakes. "Well, I mean, it's just applied chemistry," he pointed out. "Besides, it's not that hard to follow a recipe. Just like doing a lab, y'know? Anyway, I should go, I don't want to be distracted while I'm making the ganache. Tell Vaughn and Z that I said hi, okay?"
"Sure. ... What's a ganache?"
Marshall laughed. "Goodbye, Corrine. If Lucas asks, yes, I'll be online later tonight."
[Totally open and distractible. There are tasty things! Come and get some.]
