My experience as a teacher was going to a new school and teaching this kid. She was bubbly, confident, outgoing. She struggled a bit with the mechanics of writing, but really creative and inciteful. She was talkative in class discussions, with a really funny, biting sense of humor, and many of her jokes were about preferring English class to math. One of those students that shorten the day.
What I didn't know is before she was hit by a car she was this quiet, studious, sweet, gentle teacher-pleaser kid. She was known for her meticulously written work, and careful, reticent nature. She was headed to engineering because math was her thing. Before she wore power business suits, and after was getting lectures from female teachers about the dress code. I really likes the kid and one day she told me the only reason I liked her was because I didn't know her before. She told me she remembered everything, from before, but she just didn't feel the same way.
So many people treated her terribly, assuming she had chosen to be different. She wrote something for my class about how she can remember being able to do certain math equations, but could no longer do them. She remembered liking certain movies, songs, but now they gave her no joy.
