Thanks, Ella - it is particularly nice for my sister as one of her four sons has cut off contact with her and his brothers without any explanation. He has no children and is an alcoholic , as is his wife.Fortunately, she is on good terms with the other three daughters-in-law and sees all her other three gd regularly as they live locally and are now old enough to drive and drop in to see their Nan.
You can imagine how we comfort each other on my visits. We have always been very close, even though we are totally different personalities. Sometimes she drives me mad, but I still love her dearly and I know I annoy her too (she calls me 'Mrs. Efficiency'). I just wish my daughter in New Zealand had not lost her relationship with her sister, whom she helped so much.
