This person just clearly made a "typo." It doesn't mean he/she can't spell. What goes around comes around. The facts are not known. Some of the people posting who worked in the schools should know more about Mr. K than the casual observer. Only he and the person's present in the meeting know why he suddenly "retired", quit, resigned, whatever the case may be.......
Guess what? there are teachers in many schools who don't have proper use of the English language, truly cannot spell and make other mistakes. They are human.
