FALSE - I received a few emails from Agents saying this Question was too easy...but I had to respond that there were about 5 percent of the responses that were incorrect. So obviously, the Question was not that easy!
When I was in college, I dated a plumber's daughter and from time to time I found myself in the uncomfortable situation of having to make small talk with the rather gruff guy. He was a "Licensed Master Plumber" with a lifetime of experience. I remember once, that I ask some inane question about the plumbing trade and he said: "There are three rules in plumbing: 1) Hot is on the left; 2) Crap flows down hill and 3) Payday is on Friday."
I am not sure if that brief lesson was meant to apply only to the plumbing trade, or to be extrapolated to cover most of the Questions of Life, but 20 plus years later, I still remember it.
Oh, and if you don't believe the Licensed Master Plumber, you can check the Florida Building Code, Plumbing Section 607.4 to confirm that hot water is on the left side of the fixture.
