If you had home schooled, would you have taught your kids the proper spelling of "grammar?" A cheap shot, but if you're going to be a spelling Nazi, don't be surprised when the spelling Gestapo knocks on your door questioning your purity.
I really learned English grammar from my French and Latin teachers... learning a foreign language is great, because it really teaches you the different tenses and their English translations, how to use them, when to use them, and all of that. That wasn't until 10th grade.
oops! I missed that typo in my zeal to post! You are right!
We all make typos in our online messages from time to time. But, making spelling errors in a thank you note - when you're the top 4% of your class - is another matter altogether.
This from the guy who misspelled his screen name?
