Dear Mary: Why don’t my neighbours appreciate my 8 p.m. Thursday firework?

Q. For me the hallmark of a really close friend is someone with whom you feel comfortable enough to bring a phone call to an abrupt halt with no need for explanation. I too am over 70, but unlike your correspondent from New Zealand (Dear Mary, 9 May) am still working full-time — now from home. Yet my telephone rings throughout the day with calls from the sort of people I might see, at most, twice a year in the outside world, now wanting lengthy chats. I could just tell them that I am still working flat-out but the problem is that these are often people I feel guilty about because, to be blunt, they are keener on me than I on them and I have neglected them, and so I don’t feel I can hurt their feelings by explaining that I need to get on. Neither, obviously, can I avoid their calls at this time.
