Ever wondered?

Ever wondered what happened to common sense? Every day more examples of a total lack of common sense jump up and slap me in the face. I expect it is because I am getting older and my tolerance level is decreasing. I wonder "Why can't they SEE how completely irrational they are?". So I'm going to highlight examples each time I update my blog - mainly as an outlet for my frustration - and please add your own. It could be quite amusing at the very least.
