Our school's speech/language clinician (also my fabulous research partner) told me that she had been working with two of my kiddos from last year. They were making a list of items they could bring to the class party the following day. In the middle of the lesson one blurted out, "But no egg at school!"
Random? No. He began recounting the egg-breaking incident from last year and reminded her that Mrs. Lipstick said raw eggs are not alright to bring to school.
If nothing else, at least they learned something last year.
