When someone was home, able to give a pseudo heimlich manuevre/punch me in the back while I was choking on water (Yes that can happen) a few years ago
dont wanna think what would have happened if no one was around :x
Alternately, I'm lucky that my final year high school maths teacher was such a goddam legend, and that the previous years science teacher quit and had a new replacement, who was also awesome. Without those two, I doubt I would have got into the uni course I did. First teacher was pretty much the best in every way, second one because the old teacher was so bad, I needed near perfect marks to get into my course and I actually failed science under him in year 10 >_<
