I am back in my classroom today, getting ready for the start of school Monday. That story just made my week! 
Oh, yeah. You will hear that story again…from his 3rd Grade teacher, his 4th Grade teacher, his 5th…you get the idea. Teachers* share* this kind of thing!
Sassafras’ story reminds me of a joke I heard once:
A man goes to the doctor because he’s having trouble breathing. The doctor examines him, scribbles something on a chart, and leaves the examing room for a moment. The man decides to peek at his chart. When the doctor returns, the patient indignantly points to the doctor’s writing on the chart and complains loudly to the doctor about it.
The doctor says, "In the first place, if you want to go over your chart, let me know and I’ll talk to you about it. In the second place, those initials stand for “shortness of breath.”
Yep, they sure do. 'Course, it requires some interpretation. Fortunately, no handwriting involved.
