That must have been so nice for your Mother to be able to go back to Shetland, and that the weather was good for her visit. I know my elderley uncle used to take great pleasure in being able to go back to the farm he grew on up, and we used to take him for a drive round, so he could point out all the places he knew, and who lived where!!
Its a shame some of your Mothers friends had passed away though.
I am sure she will have brought back many happy memories of her holiday.
