Question Author
As usual, obNOXious has the insight to understand where people are coming from! For your information zzxxee (that name sort of lulls me into a bored snooze!) I am a grandmother! When mentioning how pretty she was, I was indeed trying to make a point, albeit 'shallowly', that she had everything going for her! Thanks Ethel for the link. I shall investigate. Thanks also to everyone else; I am sure you are all right. I have enough problems of my own, without taking on those of a total stranger. I received a big bunch of flowers today from the lady in question, thanking me for my help. I shall assume that gesture draws a line under my involvement and I shall leave her to find her own way. Any advice I offer will be to the neighbour, and then only if he asks me.
It's really helped to read all your responses, even yours, zzxxee. Thank you.
