I posted this comment on Abbie's space and felt the need to share it further:
It's funny that you mention feeling better at the expense of the moronic behaviour of others. I encountered a young man (22 or so) in a Super Walmart who worked in the pet supply and fish departments. During our rather long wait in line he babbled on about how some of his customers that day were "so stupid, it makes even people in Missouri look bad" (where he was from). I couldn't help but judge him based on his own ability to communicate both verbally and through body language and come to my own conclusion that he too was lower on the intelligence chain. My step-son and I exchanged glances with one another throughout the conversation simply to affirm our internal reactions of "Whoa, this guy is an idiot." After making our purchase and exiting the store, I sensed the desire for both of us to begin nailing the poor guy with snide criticism, so I quickly took the opportunity to be a good example with a short and simple explanation. "There are a lot of people in this world. I don't know where that guy is coming from in life. He's definately 'different' from most people we encounter, but we shouldn't treat him any differently." Both of us paused in reflection. Recognizing that I had squashed what my son and his friends may have made into an entire week of humorous conversation, I added, "But, it's still funny." (and we both chuckled at the young man's inability to see himself in the same place he was putting others)
