My mother was my Language Arts teacher from sixth through eighth grades. I was afraid to get less than an A in her class–and it was a challenge in the beginning, because the school I attended before sixth grade never introduced grammar in any form. She taught me well, though; I went on to major in English in college and graduate school. To this day I am unable to keep myself from proofreading the newspaper as I read it.
