I have to admit, I do that rather often. Because people's ignorance can really be astonishing sometimes. The problem with "Common Sense" is that it's not that common anymore at all. Ignorance often ends in accidents, or irritation or damage of some kind. With regard to acts of ignorance, I sometimes wonder how we made it as a species this far?
Like this morning, I noticed a truck attempting to reverse into a rather tiny goods delivery entrance lane. The truck driver was completely in the right, indicators on and reverse alarm sounding etc. In comes this idiot, squeezing past the back of a reversing truck with a rather tiny car.
Nothing happened, I just thought that was a rather stupid and unnecessary chance to take. Apart from all else, there was no way the truck driver could've seen the tiny car!
Do you notice people's ignorance? Have you seen something in particular that made you go WOW recently?
