Left-Field Thinking

(My mum is admiring my new sketchbook. I’m right handed, while she’s left handed.)

Mum: “I like this book, but it’s too small. I find I smudge the pencil across the right page, because I start on the left side.”

(I silently take the book, and turn it upside down.)

Mum: “…for a smart woman, I can be really stupid sometimes.”
