Grade Four, I was in line for the check out at the supermarket and this very pregnant lady was in front of me. She was talking to the check out chick about this baby and how they'd gotten all the clothes and everything for it. I asked her out of curiosity when exactly her baby was due, and that was when she told me she wasn't pregnant. (She was just very, uhhh, plump). I grabbed my things and walked away.
Another time was in Year 9. We were in Drama class and I was talking to friends about future ambitions and possible career choices, when my friends told me that I should become a doctor. I then gave them reasons why I could never be a doctor. One, that I could never give other people needles because I myself hate them so much. Two, if I became a gynacologist I could never perform a pap test. Three, I could never be a surgeon and have someone's life literally in my own hands. And the one I dwelled on most was the fact that I could never diagnose someone with cancer and tell them that they were going to die in a short matter of time. I evaluated more on this, but suddenly stopped because I remembered my teacher had just been diagnosed with cancer. I literally walked out of class due to the awkwardness.
