I graduated high school in 1970, and in my class was a fine young man whom we'll call Scott, mainly because that's his name. Scott has a PhD and is a regular contributor to Psychology Today, which is not terribly surprising as he's a LIBERAL with an executive membership card and the official thermos and lunchbox.
A good friend of mine who shall remain nameless has a FB account. Upon reading one article that Scott wrote, he pondered the significance for about ten minutes before he was distracted by a naked woman running around his front yard holding a For Rent sign.
One way or another, Scott was encouraged to write a follow-up article, and did so, which my friend also read. Instead of ignoring the entire business, he wrote a response, posted it, and a few hours later discovered that Scott had deleted his thoughtful missive and blocked him on FB. He was surprised - I wasn't.
