My friend Abigail is like this. Both she and her husband Simon have some chronic health issues which she seems to think are fascinating to other people.
She is a lovely, kind person and devoted to a demanding husband who needs (or wants) a high level of care from her (despite her own poor health), but the particular habit I am about to describe can be a bit wearing.
The moment you meet her she excitedly launches into mundane stories about visits to hospitals, GPs, physiotherapists as if they are exciting and fascinating adventures. She genuinely seems to think that friends and acquaintances are anticipating her medical news like you would the next episode of exciting soap story or television drama.
Once a month Abigail and I and two other friends Joanne and Nicola, meet up with other female friends. We usually go to a pub or restaurant and the four of us take it in turns to drive, because we live within 10 to 15 minutes drive of each other and being a big, geographically spread group, the meetings are sometimes as much as 20-25 miles away.
Depending on whose turn it is to drive, where we are going and which order we are picked up, I might hear the full Abigail and Simon medical update up to three times before we reach our destination where we hear it again for the benefit of the friends that didn't travel with us.
It is quite often the case that during the journey the only person to utter a word beyond "Hello, how is everyone?" is Abigail. She is an expert at avoiding pauses long enough for anyone else to speak.
Occasionally, she will pause to breathe or cough for long enough that I might ask Nicola,
"How are you and Mike?" To which Nicola might reply.
"We are are fine, we had covid a few weeks ago, but it wasn't too bad."
Abigail will jump in with something like "When I had covid I was so ill, I had to call the doctor out in the middle of the night..." the boring details (which we have already heard numerous times) will be repeated before she continues with the latest fascinating episode of the Abigail and Simon medical show.
We are all on a WhatsApp group that we use to arrange the monthly meetings. Sometimes, after a meeting we get a further update on the WhatsApp group, something like,
"When I got home, I found Simon lying in bed with a headache, I called NHS Direct. They suggested I give him a couple of paracetamol and see how he is in the morning. Thank you for a lovely evening, it was great catching up with all the news...".
