I don’t think of myself as snitty about grammar. Yes, I have a Ph.D. in Literature and Creative Writing, but I don’t sit around critiquing friends’ emails and Facebook posts. I don’t use red pen on student homework unless it’s the only thing I can find in the bottom of my granny purse or the cobwebby corner of a desk drawer. In a moment of haste, I too have inadvertently typed “it’s” for “its,” or lost my way in the thicket of there, their, they’re.
She who has not split an infinitive cast the first stone.
That said, I do enjoy moments when language shows evidence of bending in a way its authors did not intend. It’s a surefire stay against boredom. The world is replete with these delightful gaffes, such as those chronicled in the "blog" of "unnecessary" quotations.
This morning, a high school’s marquee flashed: “Come here / wonderful music.” I didn’t pause to read the other screens, which must have included info about an upcoming concert. I liked that the first screen was, in fact, a curling index finger beckoning “wonderful music” to visit the school. Come here!
