growing up to be a teacher

On the day she earned her qualifications Mother gave her this flashing keyring that said TEACHER on it and she thought that must be her way of getting back at her for all those times she shouted "You're no Teacher! You teach me NOTHING" at her. As Irony has it, later her little sister would spit those same words and she would just smile and blink the keyring with a lifted eyebrow. At this unshakeable proof of Wisdom her little sister would let out a snort and show her polished middle finger in response. What a smart young woman she'll grow up to be, she thought.
