If you think a semicolon is a regular colon with an identity crisis, I will not hire you. If you scatter commas into a sentence with all the discrimination of a shotgun, you might make it to the foyer before we politely escort you from the building.
Some might call my approach to grammar extreme, but I prefer Lynne Truss's more cuddly phraseology: I am a grammar "stickler." And, like Truss — author of Eats, Shoots & Leaves — I have a "zero tolerance approach" to grammar mistakes that make people look stupid. . .
