There are two types of fools.
First, there is the harmless fool. Harmless fools, like myself, are those who do dumb, trivial little things throughout the day and don’t even realize it.
From my own experience, we harmless fools will do something like forget where we put our car keys when we just put them in our pocket, or make the mistake of saying something to a girlfriend along the lines of “Boy, you haven’t worn makeup in a while have you?” and not realize why that might make somebody mad.
