On the car ride home, Derek and Sonya argued about who should transform first.
"I found the shop," Derek said.
"I found the collar," Sonya said.
"I bought it," Derek said. "I'll be very angry if I don't get to try it on first!"
"How do you know I won't just turn you into a frog to spite you?"
"You'd never do that."
Sonya sighed. "You're right, I wouldn't. But I will try to make your transformation as appealing to me as it is to you."
"I'm willing to be almost anything as long as it ISN'T an amphibian and can still speak English."
They stopped for a moment and pondered in the silence. Derek was the first to start laughing.
They drive to Sonya's home because she have a own flat.
Later in the flat Sonya suddenly pull the collar around Derek's neck.
He said: " thanks that I can go first."
Then she said: "I want to test it first"
