My primary degree is in engineering of the electric/electronics variety, which is why I can fix LED lights, for instance. I suspect an engineering degree gives you more of a theoretical understanding rather than practical knowledge. I mean, I’m no electrician. At times, I take on projects where I may have been better advised to call an electrician.
Recently, our maid’s instant water heater died, and some action on my part was indicated. Though an engineer, I have been in the corporate scene long enough to know that the right response to any action item during a meeting is, “May be by next Tuesday.” So I asked the maid to use my mother-in-law’s bathroom, thinking that I could postpone this issue to one of the future Tuesdays. But the maid, probably bound by some sacred ethical covenants of her profession, refused to do that. At that point, I should have called the electrician. But I foolishly decided to take a look at the prima facie evidence. The switch looked fine, with its indicator light coming on as expected, but the water heater remained intransigent.
