Gold there is, and rubies in abundance,
but lips that speak knowledge are a rare jewel.
March 4 is National Grammar Day. After spending four years getting an English degree (and working in the English department), I just can’t pass this day up. You can get information at Grammar Girl’s website here (including writing contests, a Grammar Day song called “March Forth,” a songwriting hall of shame, etc.).
Now today is not supposed to be the day of the Grammar Police. Instead, National Grammar Day is a day to celebrate the fun quirks of language. However, if you happen to need to correct someone, I recommend using some Shakespearean insults. Perhaps “‘Thou churlish motley-minded jolt-head,’ you wrote ‘should of’ instead of ‘should’ve!” or maybe “More of your conversation would infect my brain.” Check out the Shakespeare Insulter for more ideas.
