Dear Mary, from Joanna Lumley: what do you get someone who insists they don’t want a present?

From Henry Blofeld

Q. The other day I went to an all-male dinner party of about 20 people in a highly respectable club. I spent the first few minutes shaking hands with most of the other people there and was horrified to find that quite a number of them kept their left hands in their trouser pockets while I did so. I was brought up to believe that this is extremely discourteous and I think it looks so sloppy. I have no idea what the official etiquette is, but I am delighted to have been given the chance to find out. What do you think, Mary?

A. The official etiquette? It is extremely bad manners to keep one hand in a pocket during an introduction – the atavistic reason being fear of a concealed weapon. Younger men may well have been influenced by images of the American actor George Clooney, who routinely keeps his left hand in his pocket during red-carpet Hollywood events.
