Mine is from the mid-1970s when my family lived near Cambridge University. My father was on sabbatical and my brother Nulli and I, the only siblings yet born, were enrolled in a nursery school.
The nursery school had a playground with a number of activities, I imagine, but the only toy I remember was the scooter.
I very badly wanted to play with the scooter, the one day I remember, and I waited throughout recess for the bigger children to let me have a turn. Sadly, they did not. They did not relinquish the thing until recess was over and we were all called inside.
That was my chance! Ignoring the call, I got on the scooter and scooted a bit.
The next part is a blank, but I remember that I was punished. The school regularly gave us milk and cookies for our snack, but that day I was not allowed cookies, and possibly not the milk either.
I'm fuzzy on that part, but not what happened next. My brother, who was only 2 or possibly 3, perceived that I did not have any cookies (or, possibly, milk) and immediately shared his with me.
That was over 40 years ago, and the reason I thought of this this morning is probably because Benedict Ambrose and I are going to Cambridge this afternoon the 4 PM train to Peterborough. (I will be working on the train, never fear.)
It's quite a lovely story: I hadn't before noticed the contrast between being oppressed, as it were, by the stronger only to be comforted by the (then) weaker.
