GeordieboyNS I have read about the “knockerup” many years ago. The book had photos of a man with a long pole reaching upstairs windows, so I knew what you were talking about. I had to think for a couple of seconds why you said crude, before the penny dropped. I often think of the word gay used to be happy, but young people would probably not know this. “Woke” used to be after sleeping. I had to explain the new meaning to my husband.
