Another Awkward Moment in A Long Line of Them

As a teacher, you hope that you are forewarned certain things about your students, or else incidents like this and this are going to happen; one of the things that requires a warning is if your student has a twin . . . but I was not warned, and so when I saw one of my particularly clever students on the stairway, and was excited that she had coincidentally used the word "anthropomorphize" in her essay-- because this was a word that came up in class that day and she was the only student who knew what it meant-- I yelled this non sequitur to her: "Anthropomorphize! You used it in your essay! That's funny!" but I did not realize that this was NOT my student, but her twin (because, as smart as my student is, she did not warn me she has a twin, so I blame her for this awkward moment) and so her twin gave me a weird look of non-recognition-- a look that said, "Why are you yelling sesquipedalian words at me, creeper?" and then she gave me the cold shoulder and continued up the stairs . . . but we sorted it out later in the day and now I am on my guard for doppelgangers.
