I believe our individual personalities are formed by age five, often earlier. I have every report card from kindergarten to grade eight. The same adjectives were used over and over by teachers to describe me - quiet, diligent, conscientious, neat, well organized, polite, reliable, and consistent. These are still me, as well as some not so flattering ones. In my family, the kids were good in school, bad at home.
Mrs. Hobbs, my grade two teacher wrote, "In her stories, Julie writes good sentences and expresses interesting ideas." Hope this still applies.
