We see this often here. Despite the education, we still see this often here. We then ask ourselves, are these people educated, maybe they learnt a thing or two about being mindful to others when they were younger? But when they grow older, those values disappear or they are overwhelmed by other pressing considerations, like the dire need to sit in the train & listen to wrinkle-removing music.
We now know why our kids find it difficult to manifest considerations towards others- because the adults don't show it.
