I'm not old, but like all of us, I am not getting any younger. Therefore those who are more senior than me, please bear with my pathetic attempts at "how things have changed," but I hope you at least appreciate the following anecdote and sentiment. Back in the early 1980s, I remember as a child going to DisneyWorld with my family. My favorite was Epcot and the stucco kiosk "nations" you could explore. Even more impressive though was the use of touch screen technology. I remember thinking, even then, that it would never be a reality. Fast forward a couple of decades and I have presently possessed a telephone (!) now capable of touchscreen technology for years, and without fail, I still remark to unfortunate listeners how amazed I am by this leap forward.
The reason I mention this, is that it must be incredible for your mom, at 92 years young, to be able to video conference her son. My grandfather was born in 1903, the year the airplane was invented. He is no longer with us, but the innovation that has occurred since then is breathtaking. Within 40 years we had nuclear technology and another 20 years later we were on the moon. For thousands of years, most people were farmers and did not leave their immediate location for most of their lives. Then with the industrial revolution, everything went into fast forward. Imagine those born in the mid-19th century, who may have been lucky enough to have their picture taken, then see the advent of trains, and telegraphs, and steam ships, and early- telephones, etc. Personally, I still can't believe the internet is thing. Every bit of information at your fingertips. History is relative but we are living within an incredible era that has witnessed change like none other; for better or worse.
Sorry for the pedantic post, but I'm a history teacher and I haven't been able to bore anyone in two weeks.
And also quarantine; it is just me and my two cats and they get tired of my lectures.
