Ancient technology and siblings

Had the singularly oddest experience this week trying to explain what a typewriter is and how it works to my youngest brother (11 yrs old). Apparently they don't have typewriters in public school anymore, he was completely mystified by the idea of an ink ribbon and even more so by a correction ribbon. Mind you, my typewriter is a nice little electric model that has all of the bells and whistles. Even so, I wondered if this is what the baby boomers feel like when someone asks them about their blog. Strange. I'm trying to explore the feeling and convince myself that I speak a valuable nearly dead version of technology language, but really, it just makes me feel old.
