Looking for Mary Poppins

Mrs S welcomed a chimney sweep into our house. She then realised he was the same chap who swept it 20 years ago (you can't rush these things). He did a great job and was good enough to tell us the chimney cowl we found in our garden was not ours - but our neighbour's (saving us the cost of replacement.).
I was busy having more chemo. There was a delay of over two hours before they started. I wasn't feeling good to start with, so this was a less than excellent day for me.
