Me: So, what are your plans after you finish year 12?
Senior student: I thought maybe the police, or Duntroon to be an army officer
Senior student: I thought about being a vet, but then I learned that they have to put animals down, and I COULDN'T do that
Me: it is something they do
Senior student: And knew I couldn't be a doctor or a nurse because of the injections and blood and stuff.
Me (puzzled): so you don't like killing animals, you don't like blood or injections, but you're considering a career where you might have to shoot people someday?
Senior student: Oh. Yes. But.
(and we laughed.)
It's such moments that can make teaching a very very amusing career. Also it generally doesn't include putting animals down, blood, injections or shooting people.
