"Mommy, my canny!" He is trying to extract a Sucrets from the blister pack. Again. Because he has the memory of Dory, the blue fish in Finding Nemo.
"This is not a candy. It has never been, nor will it ever be, a candy. You don't like this. You've done this before, quite often in fact, and you have never liked it and have always spit it out."
"Mommy, my canny! Pwees!"
"Fine. But just please try to remember to bring it back to me when you learn again what the phrase medicinal lozenge means." And with that, I hand him the shiny red throat drop.
"Okay, Mommy." And off he goes, with a Sucrets in his mouth. I expect to see him again in about a minute and a half.
*UPDATE* His mouth in empty. Somewhere in the house, plasticised to the carpet, is a Sucrets with my son's teeth imprint in it. Because I have the memory of Dory, the blue fish in Finding Nemo.
