Because I do. All the time and everywhere, I said.
Every night for the past week when I’ve been preparing for bed, I’ve thought about how the striped toothpaste might possibly… and then I start brushing my teeth, because when you rise at 04:30 in the morning, you’re too tired for that sort of things.
But yesterday I got fed up with just thinking about it. I used a toothpick to make some kind of fan pattern (on the left) and some sort of double comb pattern (on the right).
