I was appalled at the contents of my sister’s handbag. It was stuffed with sweets and chocolates, from Werther’s originals to a type of Walnut Whip crossed with a Cadbury’s Creme egg that I had never encountered before.

My sister suggested that I offered this big chocolate treat to the Jewish Hungarian girl with the Manchester accent who was perched on the back of her bike. My sister was this child’s babysitter for the whole summer holiday.
