I was late for my 9am by about 20 minutes. Here's why:
I got out of the shower at 8:50, and saw that I had 10 mins to get to my lecture. I fired up the engine on my racing bike, and rushed the journey (normally 15 minutes) in about 7 minutes, arriving at the building at 9:02. I was so knackered by my ride that I spent about fifteen minutes catching my breath and trying not to vomit (I succeeded). I hadn't had breakfast.
It turned out that the lecturer had spent about fifteen minutes explaining that there are different sizes of grains in soil, and that some of them take in more water more quickly etc than others. Woop.
