I was a teacher’s aid at my son’s school, and I sat in on his class one day as a first-grader did show and tell. She held up a book and said, “This is my diarrhea!” Half the class looked confused, the rest looked intrigued. She continued to mix up “diary” with “diarrhea” for several more sentences as the teacher and I were silently crying with hysteria.

If just one kid had laughed, we would have jumped in, but everyone listened with respect and applauded at the end, so we moved on.
