"Because I wanted to grow fat."

"You grease-tub! Oh! my teeth and tail! I thought you were a humbug!
Why did you want to get fat? There's no truth to be got out of you
but by cross-questioning. You ain't fit to be a horse."

"Because once I am fat, my nature is to keep fat for a long time;
and I didn't know when master might come home and want to see me."

"You conceited, good-for-nothing brute! You're only fit for the
knacker's yard. You wanted to look handsome, did you? Hold your tongue,
or I'll break my halter and be at you--with your handsome fat!"

"Never mind, Diamond. You're a good horse. You can't hurt me."

"Can't hurt you! Just let me once try."

"No, you can't."

"Why then?"

"Because I'm an angel."

"What's that?"

"Of course you don't know."

"Indeed I don't."
