There is a new series on Netflix called Maid. It's about a young woman (white) who is involved with an abusive husband/boyfriend. She ends up leaving with her toddler daughter. She is completely broke. Her parents are useless. The only way she can make money is as a maid. Like your grandmother, she is very bright. Her first customer is very wealthy. They have a huge beautiful house on the water. The customers she cleans for are black. The woman is a little snooty but you can tell she is a good person and in the end, she is generous to the maid. I wish you could have watched that show with your grandmother. She would have loved it.
