From 8-year old Hilda’s diary:

This afternoon Alma took me to the park and while we were there feeding the ducks, I asked her why grandmother sleeps with grandfather, if good women are not supposed to sleep with men. Alma got very excited and asked me who had been filling my head with such naughty ideas. I told her that Gladys said that about Suzanne and she said that Gladys had no right to talk to me of such things. She said that Grandmother was a wonderful woman and has a right to sleep with Grandfather because he is her husband and she said that I mustn’t thing of such things again, that real ladies don’t think of such things.
