We agreed that that first cone was the best. But that didn’t mean, Sam argued, that the place itself served the best ice cream. With lawyerly precision, he noted that we each had tried the same flavors to compare the quality of the various shops. Jessica always ordered the lemon meringue. Sam always ordered the white chocolate and the tiramisu. (These are amazing flavors, huh?) And I always ordered the standard chocolate and the pistachio (note: nuts). I don’t recall if this was a rule or a guideline or just something we happened to do.

Sam grilled each of us on which shop served the best version of our control-group ice cream. When tallied, a place other than the one where we got the first cone triumphed in a landslide.

Jessica contested the results, citing the incontrovertible fact that she disagreed.

When we returned home and Jessica learned that I had written that the first cone had hazelnuts, she dug in her heels. “You are confusing the flavor of the coffee and the crunchiness of the chocolate shell with nuts,” she told me.

I checked with Sam. “I remember it was crunchy,” he said. “But that could have been the chocolate. It may have had nuts. I just don’t know.”

Smart kid. When caught in the middle of a fact-check dispute between parents, agree with both of them.
