"Now the current problem is this..." Jess says, thinking things over. "Just why the hell are you lactating?"
"I dunno. Don't cows make milk?" Mary shrugs her shoulders.
"Not all the time. Only when they have calves to feed. Just like humans with babies."
"Hmm. So maybe my body just needs a calf to feed!" Mary suggests, looking at Jess with that certain expression on her face.
"Yeah, maybe... no. No no no. You are not thinking what I think you're thinking." Jess steps back, shaking her head vigorously.
"Please! It'll only be until I stop lactating, and if it doesn't work, I'll change you back lickety-split! Honest!"
"This is crazy. You can't just expect me to... to..."
"Any crazier than turning into a cow in the first place?"
"I... I..." Jess stammers, thinking it over feverishly.
