Seriously. In the past couple of weeks, I have encountered people well into their 20s and 30s who seem to have no idea about 'common' things. The most recent memorable instance: A 25-year-old co-worker didn't realize there was an "extra tire" in the trunk of her 2-year-old Saturn. Have you encountered these types of people? How do stupid people get by in life? Is it the kindness of strangers?
