Setting a bad example

So, I am renowned for getting into all sorts of unusual sitting positions on office chairs. When I was working at James Cook University, one of my colleagues one day goes "who am I?" while he did some kind of contortion act on his chair (that's when I first realised I was a noticeable odd-ball). Anyway, one of the ladies who works here part-time just popped in with her two little girls, who look to be about five and four. They walked past my desk and when I said hello the slightly taller one said to me "are you allowed to sit like that?", because I didn't exactly have my bottom firmly planted on the seat. Probably not. So I straightened up and sat on my chair properly - till the children left.
