Lampposts...................................

"Smartphones have been ubiquitous for years, of course - but much more recently, there seems to have been a shift in social norms.  For many people, the unwritten rules of sidewalk choreography now include this:  If what I'm reading or watching on my phone is sufficiently interesting to me, it's entirely up to you to get out of my way, just as if I were very frail, or three years old, or blind.  Or a lamppost."
-Oliver Burkeman
