(Valediction: “a farewell, a bidding farewell,” 1610s, from past participle stem of Latin valedicere “bid farewell, take leave,” from vale “farewell!,” second person singular imperative of valere “be well, be strong” (from PIE root *wal- “to be strong”) + dicere “to say” (from PIE root *deik- “to show,” also “pronounce solemnly”).
My daughter graduated from homeschool high school at the end of May and is headed to college in the fall. For seven years, through middle and high school, I taught her math, science, and arts every week, plus a bonus-senior-year literature class. As this means that I am also graduating, in a sense, or at least retiring, I thought I should be allowed to make a speech. And since there’s no one around to stop me, here it is. I’ll keep it short.
