Hate to bring this to the top, but I wanted to add my two cents. When I was taught English grammar (in the old days), I learned the rule about periods and quotes as some of you mentioned here - inside if the quote was a complete sentence, but otherwise outside to end the sentence. It seems the rule has changed, and now (at least in America) periods always go inside. I learned the hard way when my children would ask me to proofread their papers in school. After they told me several times that I was doing it differently than their teachers, I finally gave up and told them I would correct grammar but for punctuation they were on their own.
Why can't the rules just stay the same? Oh well, I guess that's life.
