I don't think you guys saying you can't spell is something to be embarrassed about. Their are misspelled words and then they're is just bad grammar. A misspelled word is ok. Your just going to run into that when reading things other people right. I bet some of you guys are having a seizure after reading this.
Seriously, after living with it and dealing with being a poor speller all my life I am embarrassed by it. I have an expensive college education and a professional background but can't spell. I guess part of it comes from being a slight type A personality and a recovering perfectionist. The three combined can make life miserable.
