Pet Peeve

Today's Pet Peeve is the incorrect use of the apostrophe.  You know, that little mark that goes between the "n" and the "t" in the word "don't" or "can't" or wouldn't" . . . . In the past 5 years, it seems, the apostrophes of the world have multiplied and now show up every time there is an "s" at the end of a word.  Today's rant was brought on by the brochure from Performing Arts Fort Worth, Inc.  This is the organization that presents musicals and plays at the Bass Hall in Fort Worth, Texas.   Several of the shows were listed as "Subcriber Add-On's!"  If you had an English Teacher in 7th and 8th grade like my teacher, Miss Dibert, you would have immediately recognized the error.  A word should be followed by an apostrophe + s, if it is possessive (the boy's dog) or a contraction (it's hot  = it is hot).

My favorite resource is http://www.apostrophe.org.uk/   The Apostrophe Protection Society.

My second pet peeve is the common response from a waiter / waitress :  "No problem."  The correct response usually would be "You're welcome."   But that's a rant for another day.
