Shame on you, Don Draper!

I can't help it. There is a grammatical error that many people make and it drives me mad. When I was a youngster in school, this error was completely frowned upon by our teachers. Today most people don't even know it's incorrect. Sadly, it is practically an obsession with me. And tonight on Mad Men, Don Draper was guilty of using it. Don Draper! Leading Madison Avenue maven, admired writer of great advertising, someone who should know better. But when his wife told him she had suffered a miscarriage a few days before, he said, "I wish you would have told me." That was it. I completely lost all respect for Don Draper. He might as well have said, "I ain't got nothing happening at the agency tomorrow."
