The pandemic has changed people. Why?

I see a lot of posts around reddit about how people say that they are a different person after the pandemic and a lot of people seem to resonate with that. I personally do not see any difference. I figured maybe it was because during the pandemic, I was living with my parents and children. I did not 100% isolate. I hardly followed the news. In my country also, the death rate was a bit less. The only thing I noticed is after the pandemic, mobile usage became more frequent. I work in education and seeing someone pop up their mobile phone during lunch time was a bit odd, we would sit and discuss about other things before.

I'm curious as to how the rest of the world was affected by it.
