Sam: (calling from the living room) come look at the ceiling wax Mom! Me: What????? Sam: Come look at the ceiling wax. Did he really say there's wax on the ceiling? I comply and am astounded to see that he was talking about sealing wax. That waxy stuff you heat and press into an envelope to seal it closed. I had to wait until Brian got home from work to confirm that he'd "The Seven Little Postmen" a couple times. Apparently that was enough for Sam to remember to look for a little red blob in the illustrations.
