My niece's young daughter recently started a blog. Unfortunately for her, mom is an English teacher. And mom's comments to her blogging daughter's posts are often reminders to pay closer attention to her grammar. I keep waiting for the "or else," the phrase I relied on so much when my own kids were that age: "Or else you'll find yourself in your room for the rest of the night." "Or else there'll be no dessert for a month."
Of course, her daughter is resisting, saying that nobody cares about grammar. But if she listens to her mother's advice, she will avoid many of the mistakes I see professional writers making almost every day.
Such as writing its instead of it's (or vice versa), there instead of their (or vice versa), and your instead of you're (and... well you get the idea).
I can't threaten to cut-off your ice cream, but I can warn you that too many of these sloppy mistakes in a cover note or article will quickly lead to fewer writing assignments.
Or will they? Seems like fewer readers today notice or care. That, I guess, is grist for another post. In the meantime, proofread carefully before pressing the "send" button. Then, proofread again.
After all, its important to you're image as a profesionel righter.
