Dear Mary: how do I stop my book club banging on about their grandchildren?

Q. At the Ludlow Piano Festival, during a Tyler Hay concert, my husband and I spotted a fascinating-looking couple who were fellow members of the audience. We longed to know who they were and are kicking ourselves that we never found out the identity of this charismatic pair. During the interval we could have approached them but didn’t want to seem pushy or pervy by just introducing ourselves. What could we have said?

A. ‘Sorry to bother you but do you happen to be a friend of Derek Duck? Oh… he gave us a jumper to return to someone he said would be at this concert but we stupidly can’t remember the name of whoever it is. We’ve asked all the other likely men here. By the way, I’m Sylvia Smug and this is my husband Cedric – and you are?’
