The picture of the grey-skinned doll reminded me of somethng from 1958-9, witzend, when my eldest brother started school aged four and a half in Leeds. My dad, who was a teacher, picked J up on his motorbike after school and rode him home. Apparently J was v quiet all evening (unusual). Eventually, having recovered from the shock of his first day (no playgroups or nurseries then), when asked about school, he said: "Everyone shouts!"
Later, in a conversation with Mum he explained that people were different colours. Mum said: "Oh yes? How do you mean?"
Bro: Well, some of them are nice brown colours, not just grey like us.
