I used to sleep over at her house sometimes on the weekends. She told me that she and her children used to play dress up; I wanted to play dress up with her too, but there were no mens' clothes left in the house (this was the early 70s, and the second of her two husbands had died in the 60s).
Also, sometimes on Sundays we would bake together. I have a photograph somewhere of a cake that we made from a metal lamb mold. We frosted it, and sprinkled green coconut around it on the cookie sheet where we placed it.
My Mom reported that one time after I came home from Nana's (Billie's) house, I insisted that my spaghetti O's be warmed up before I ate them. My Mom apparently always served them to me cold, but my grandmother had given them to me warmed up, and I thus learned that I preferred them that way.
