I teach on a campus in southern Florida. I have given up saying a friendly “hello” or “good morning” to students passing me on the walk because they are not even looking at you... they have their eyes buried in their electronic gizmos (including the ones who, if you are not watchful, will walk into you).
I’m a grad student now (in my late 40’s), so I see this all the time. I think it’s pitiful. These kids have no idea how to relate to anyone face to face. Most of them seem to have the personalities of neanderthals.
I am grateful that I grew up in the time that I did — a time w/o all computers, cell phones, and i-phones. We really lived life and actually interracted with others in a meaningful way.
