Oh my goodness, something similar happened to me. My teacher got sick the first semester and we had a sub. After Christmas the sub stayed and we were told our teacher had passed away from cancer. It really affected me because I lost my mom when I was three. So to lose two highly influential women by age 5 was a very difficult thing for me. I had a lot of nightmares after that for quite a while. I really liked the sub, though. She was real sweet.
