We have misspelled signs like that all over our school. Most are created by teachers. I do go around and correct the spelling. In fact, I had to correct two for the "College Fair" the week before Thanksgiving. One was spelled "Collage Fair". The other was "College Fare". Both were done by the teacher in charge of the college prep courses and who happened to be last year's teacher of the year. I was reprimanded for making the corrections as it was (apparently) humiliating to the teacher. Then again she is always sending emails out with misspelled words, poorly structured sentences, and lacking any form of punctuation. Oh, and the signs were approved by the principal and had his signature at the bottom. I guess he didn't proofread them either. Yes, I work with idiots and I do fear for the education of our youth.
