I made a batch of cookies last week which I mixed out of order and didn't blend well; the result was quite lumpy and uneven. He was over when I was making them, and tried one.
"How was it?" I asked.
He thought for a moment, and then said, "About as good as most peoples' homemade cookies. Which is to say, a little worse than your usual standard."
... now that is a backhanded insult. (Forehanded insult?)
I sent him home with the first sheet of them (as had been prearranged in exchange for him refilling my cookie supplies). Later, we were talking about them, and he said,
"I liked them because they were all different."
"No, really! It was like, 'Ooh, this one's more like a butter cookie!' and 'Ooh, this one's more like a sugar cookie!'"
And he sounded so earnest in his delight at getting all these different kinds of cookies that I had to giggle.
