Dear Mary: How can I protect my sick husband from his friends?

Q. My husband is, in a word, adorable. However, following a substantial brain operation, his doctor has told him that to make a full recovery, he must rest in bed and stay very quiet with no visitors. Unfortunately, he is still sending out texts and emails to friends and colleagues who then get the impression that he is well enough to visit. They turn up at our flat, insisting they will only pop in for ten minutes. but inevitably staying for 30. While it is moving to see how much he is loved, seven visits equals three-and-a-half hours per day. I am not a confrontational person and don’t wish to shut the door in anyone’s face. How can I stem this tide without causing offence?

A. Let him recuperate instead at a spa-type hotel at an inconvenient distance from Geneva. At the Hotel Royal, Evian, for example, the dreamy days of respite could be supervised by a pop-up local brain specialist and the tide of well-wishers would be put off by the 150-minute round trip necessary for a ten-minute ‘pop in’.
