How many times a day do we throw around words like "dumb", "idiot", "stupid". Probably far more than we label others "Smart" "Intelligent" "Wise". But, people are not as dumb as you think they are...nor are they likely as smart.
We're all wading around in the same giant swimming pool. Some are enjoying the sun, chatting with others. Some are splashing and harassing others, and some are desperately trying to get to the edge.
