In our household, we have a set of rules. These rules have been learned through experience. They have been proven through testing and trials. They stand as timeless and proven. They apply at every age level and in every circumstance.
Rule #1 - Don't be stupid.
Rule #2 - People are stupid.
Rule #3 - I will defend your honor but I won't defend your stupidity.
Today I have found an addition that meets the previous qualities:
Rule #4 - The will to be stupid is a very powerful force.
Rule #5 - The ability to overcome Rule #1 is to conquer the will to be stupid.
(Thanks go out to Lois McMaster Bujold for Rule #4 and #5.)
