If they've retired, doesn't that mean they should be pretty burnt out from teaching children? Especially subs like my old Spanish teacher (she made me LOVE learning Espanol!!! We all thought it was hilarious because she was originally from Puerto Rico and when she was learning English in school she used to cheat on her English exams, so she'd be like, "Don't even THINK about cheating on one of my tests. I know ALL the tricks! :lol Anyhow, she was in her early 70s when she retired, than she came back to the school and started substituting. It's the same with a lot of teachers. I woudl think about 30 - 50 years of teaching, even the teacher who absolutely LOVES children, and lives and breathes for educating them would be so tired. Thoughts?
