I introduced limits today in Pre-Calc. The class ended with two girls shouting, "The limit does not exist!" More lapel pin coordination today.
Another vote for that shirt. I think it demands a Windsor, since that appears to be a dfih, and, to my eye, isn't quite wide enough. Though, given that, I'd probably go with a more sedate vest, or a more formal tie, or both, given the innate, linear, symmetry of the half Windsor, so that throws the whole thing out of whack. This could lead to a morning where I continue to approach leaving the house, but never actually do. This hyperbola, without hyperbole, cod lead to an educator's early dismissal. I may be arguing over iota, so I will make a simplifying assumption, allowing me to dispense with halving measures, and declare you perfectly well dressed, for all practical purposes.
