I had a minor plumbing repair to do in our bathroom under the sink and within the vanity. For part of the operation I needed a second pair of hands so I enlisted my wife, the esteemed Señora Robin. She came into the bathroom and sees tools scattered around, the contents of the vanity stacked untidily in a corner, and me with my head stuck under the sink.
With barely a pause as she walks in she says, “You cannot possibly know what you are doing.”
This brings me out of the depths of my plumbing cave with a quizzical look on my ruggedly handsome face.
She continues, “I see no butt crack. It is a job requirement.”
I worked for some plumbers one summer in college. They told me there were only three things that I really must know: water does not run up hill; you get paid on Friday; and never chew your nails after a job. Apparently there are four.


I have not real gripes with book. It is not great; it is not bad. There are not a lot of resources out there to use to study for the OCP Developer exam. This seems to be one of the few resources out there outside of one of the exam prep companies.
