"Trivial" is the new "MacBeth"

There was an amusing incident in tutorials last week that I forgot to mention in this space. It occurred on Wednesday, which was mostly sunny except for a quick torrential downpour for about 15 minutes in the morning and then an even more torrential downpour for maybe 20-30 minutes during one of the afternoon tutorials. It had started to rain pretty hard, and while I was explaining a problem, I mentioned that a certain part was "trivial". With exquisite timing, we immediately witnessed our first thunderclap of the day as soon as the word got out of my mouth. It was loud enough that it startled me, which I suppose helped make the whole incident even more memorable.
