Just call me the resident expert...

My job is a unique one, in that I wear a lot of hats, and they are constantly changing. I could be called on at any moment of any day to answer any question, ranging from the periodic table, to algebraic equations, to the uses of relative pronouns, to how to determine the volume of an irregular object, to explaining the nature of sin and the gospel. I think I'm going to start referring to myself as the "resident expert," although I'm discovering I'm not an expert of much, besides royally flying by the seat of my pants...
