Curious if you have a sense of how long this has been going on. My perception is that various sorts of rudeness and inconsiderateness have been on the rise for a while, but really jumped post-COVID.

Some of it is minor but just suggests to me that many people lack any sense that they should be aware of others around them. Just today I was walking down the street and a woman was stopped, in the middle of the sidewalk, staring at her phone. She was in front of a shop door but not right in front of it, so she was half-blocking both people passing on the sidewalk and people trying to get into the store. I see this kind of thing so often now, in store aisles, on sidewalks, etc., and a part of me wants to go up to these people and inform them that there are other people around them and that if they want to take a moment to look at their phone they should step to the side.
