Dear Mary: how can I duck a friend’s expensive birthday party?

Q. I must be the only person with this problem but I would really welcome a solution. I have a lovely neighbour in the flat below who happily has my dog to stay when I go away. She also holds a set of keys to my flat so she can check all is well. This time I came back a day earlier than expected and couldn’t understand why my neighbour seemed flustered and embarrassed to see me. Now I find that my home massage gun, which I use to de-tense my neck and shoulders, is missing from my work table. I can only conclude that my neighbour couldn’t resist borrowing it, had meant to return it, but was flummoxed by my early return. Of course I forgive her but how can I possibly save her face? – Name and address withheld

A. Why not cheerily ask does she by any chance still have the dog’s massage gun – which you suddenly realise you must have given her, along with his basket, lead and food?
