"Who ... Fred!"
"Margaret?"
"Y-yes."
"Your voice is different."
"So is yours. At first I couldn't think who was speaking to me!"
"It's strange it took us so long to realize that our voices would be different."
She said shakily, "We're more accustomed to thinking of how we look."
He was silent. His mind had been on the same thing.
"Your new voice isn't bad, Fred," she said after a moment. "I like it. It's a little deeper, a little more resonant. It will go well with your personality. The Doctor has done a good job."
"I'm trying to think whether I like yours. I don't know. I suppose I'm the kind of guy who likes best what he's used to."
