If the principal did pause a bit and the listener failed to pick up on that, who is at fault? No one surely! If we were to write exactly what the principal was saying, at least we could have written out "The meeting is on, tomorrow".  
My daughter does well in spelling and her teachers are pretty strict about that, no doubt. Seems like to me our kids today are slowly becoming of their own language, similar what we call the phonics or "Afro" language which name escape me right now. Anyone who are hard core rappers would even speak "rap" sentences and it's bothersome for me to understand it. Like some one mentioned, "dumbing down" the language is right.
I love the fact someone here mentioned that parents should take an active role in their children's reading and writing...spot on! I even correct my daughter's writings as well so it can be understood by another reader. Not easy I am sure but once you instill that into them, they take it in their whole lifetime and pass that knowledge and your teachings to their kids. 
Proofreading is another lost art as well. 
I believe cursive should be continued since many business jobs or contracts to be signed, everyone's cursive writings are different. If everyone prints, it gets a little harder to figure out if you actually did print out your name if the contract should be null and void because the cursive signature could not be matched. Has anyone thought about that? Our forefathers didn't print their names, every one of them on the Declaration of Independence have their own unique signature and it should be today. We all have unique signatures that stand out from others. Even court, judges, juries and lawyers love to grill someone who is forging the signature of checks and got caught when it does match.
