Unlike my son, born in the era of digital cameras and phones, there are few photos of me from my childhood years, and even less of me as a teenager. I do have one with my mother and two of my brothers, taken on Xmas Day 1976 when I was a surly sixteen-year-old. *Gulp*, my son is sixteen this Xmas!

The local dog club where I'm a volunteer instructor runs a training season-ending Fun Day with events like Fancy Dress, Agility Slalom, Waggliest Tail and other novelty races that change from year to year. One of my favourites is the Sack Race, in which my dear old dog and I always placed third.

I found Selby's Joke Book in my teenage son's bookshelf. Inside the front cover, there were inscriptions which told me the book had once belonged to a young girl, Grace. Judging by the handwriting in pencil, phonetic spelling, and her knock-knock joke, Grace was very young when she wrote in it.
