When I joined the writers' circle it was only six people, and one of those was away travelling. Then she came back and another one disappeared. One more joined and hogged the meeting. The member who had brought him had a quiet word which he obviously took badly because we never saw him again.
Then another member returned to England for major surgery, and though we are in touch with her by email, it looks as if she might not come back, and another long-standing member has gone to her homeland for the summer - her husband doesn't like the heat here.
The social life on Tenerife is like this - it is common for people to spend a few months or years here and then vanish. It can be disconcerting or exciting, depending on your outlook, but it makes folk reluctant to invest too much in friendships, knowing they may not last.
Anyway, now we are down to five. One writes books on how to deal with various chronic health conditions with diet and life-style changes, one is writing a diary of her travels in India, another has written a log of his lone Atlantic crossing and is now experimenting with short stories, I write novels, and another writes poems for children. She is off on her travels soon, which will reduce our circle to a square. We may have to advertise!
