1. Excuse, please. Guys, it's "excuse me , please." Every time I hear this on the train I have to fight the urge to reply, "excuse who ?" and not move aside. 2. Pronouncing the word "liaise" as "lie-us". It's pronounced "lee-eh-zz", not "liars". I swear if I hear someone call me a liar(s) again I'm gonna punch him/her in the ear. 3. Could of, should of, would of, must of It's could've, should've, would've, must've . Why the hell is that so hard to get??? Signed, Ted Your Friendly Neighbourhood Grammar Nazi
