Sunnyday, I didn’t think you were bad tempered - just hot and sticky and worried! I left my own car windows down once and had a sense of humour bypass with myself over it.
I’m so glad to meet another Mrs Bird fan, I think it was a first novel and I do hope she writes some more. You are thinking of the right book/film - I watched it last night. It reminds me to get some more letter paper so I can start writing letters again.
Have you read a The Guernsey Literary and Potato Peel Pie Society? Or Ella Minnow Pea? I think I like books with letters!
