Just because we're not commenting on them doesn't mean we're not reading them - and enjoying the test!
An old joke, retold as recently as http://www.madisonrecord.com/arguments/224033-the-day-the-toast-wasnt-burnt
"The story is told of the seven-year-old boy who never spoke. None of the specialists his parents had taken him to see could identify the source of his silence. Then one morning at the breakfast table a voice exclaimed: "This toast is burnt."
Their son had spoken at last! The parents jumped for joy, hugged their offspring and phoned friends and relatives to share the news.
As the excitement ebbed, curiosity grew and the mother inquired: "Son, why have you never spoken before?"
"Gee, mom," the boy replied, "up 'til now, everything's been fine.""
