Q. My mother-in-law is getting on a bit now, and

is not the woman she Was. On recent visits to her house, she has served my husband and me with only partly defrosted chicken (which we then had discreetly to dispose of without eating it). Now she has agreed to have our four children, aged four to ten, to stay for a few days while we are both away on business. How can I prevent her from giving them foodpoisoning in our absence without hurting her feelings?

A. The elderly are less susceptible to food-poisoning than the young their stomachs having been strengthened in early life by, multiple exposure to slightly 'off food, which explains why your mother-in-law does not regularly, go down herself Your children will simply have to pretend to have become vegetarian for the duration of the visit to their grandmother. Even the insensate will find it very difficult to poison their guests with vegetables.
