As most of you know, I have zero tolerance for incorrect grammar. For the first time, I did something about it.

My biggest pet peeve regarding grammar is not when someone misuses "your" and "you're," or "there," "their" and "they're." It's when any kind of professional writing, from advertisements to stories in newspapers and online columns, is fraught with grammatical errors. Aren't there editors that notice these mistakes?!

At first, Reebok's "Run Easy" campaign hadn't been bothering me. In fact, I kind of liked it -- if you take the red line inbound between Harvard and Central and face west, you see an ad perfectly timed with the speed of the subway car. However, when walking back from work, I came upon an ad egregiously reading, "RUN EASY BOSTON."
