I was shocked to discover something my 14 year old son does at other people’s houses. Something he would never do at home. Various parents had hinted at this, and I refused to believe them. But last night, Daniel confessed. After a meal, he will take his plate, cutlery and glass and stack them in the dishwasher! He will also ooze with politeness and charm to the extent where some mothers are almost swooning. His friends have done the same thing when visiting our house, but I just can’t imagine Daniel doing this. Why has my incessant nagging backfired?
