Thanks for your helpful advice, Rachael. I should perhaps explain (but not of course seek to excuse) my omission of the commas in 'why oh why'. It was deliberate, and was intended to emphasize, in what I hoped was an amusingly satirical way, the formulaic nature of the phrase. 'Why-oh-why' might, on reflection, have been better. In fact, perhaps I was moving towards the as yet unknown (to me) 'YOY' without realising it.
I haven't looked at 'The Archers' message board recently. I used to do so regularly - in fact, I once actually joined (under the name 'Theosebeia') , but was kept in pre-mod ('-modd'?) for what seemed to me to be an unreasonable length of time, so I gave up.
I do hope posters are treating the current melodramatic, boring and depressing story line with the scorn it deserves.
