My aunty once told me how embarrassing she felt when her granddaughter said loudly in a tour bus "granny, you don't know how smartphones work"?. She said she is lost in this world. I visited my aunty. Her home seemed like it had everything she has ever laid her eyes on. She bought a book on how to get rid of memories. "Pick up a thing and ask yourself: do I like it? If not - throw out". Well in my case everything stayed.
