I'm only correcting so that in the future you won't make the same mistake, and portray yourself like an idiot. In which case, you're welcome. I apologize that your English teachers failed to do so. If you're going to call me a "Grammar Nazi," then why do you capitalize the first word in your sentence, and then end it with a period if you're not going to use the contraction, which is needed to say what you mean? Unless... You don't know when to use contractions?
