I think there was a major technology boom that began to affect us in the late 80s, when personal computers came out.
I feel as if my father and I basically grew up in the same world. There were cars, trucks, airplanes. They all ran on gasoline. There were telephones and tape recorders. There were refrigerators and gas ovens. There was heating. (Maybe he didn’t have AC).
But since I was a child, the world has changed radically. We still put gasoline in our cars, but that is about where the similarity ends.
So it is hard to feel very exotic for remembering 10 cent milk, when people 30 years younger remember no computers or cell phones.
