Here's a closer photo of it.
I met a friend here today, a retired teacher like me. We sat for quite a long time, she drinking tea, I drinking cappuccino, both of us nibbling shortbread. We discussed many things, including the beauty and sweetness of our grandchildren. We looked out at the Edinburgh skyline. She said meditatively, "Do you know, I think this is probably more fun than teaching."
I think she may have been right.
