Thank you so much! That's a personal favorite of mine...

For me, and because of the fact that school doesn't emphasize it, I learned a lot of my grammar and punctuation through osmosis: reading, reading, reading, all over the board, noting patterns and applying them, testing them out to see what was actually correct. And then I had to go back and take a class, and put names to all these rules I already knew but couldn't convey very well because I didn't know what it was all called. I just knew what looked and sounded right.
