Most people would think: "this is my last chance to do all those things I don't get time to do when I'm working." They'd be running around visiting exhibitions and movies, seeing friends, painting the bathroom.
I think: "this is my last chance to spend a whole week doing absolutely nothing." I believe I may even have discovered a whole new paradigm of sleep - the more you sleep in the day, the longer you sleep at night.
I first learnt the American term "goofing off" when I spent a fantastic summer in Michigan with my dear aunts and uncles. This is me goofing off at age 11 with my Aunt Ina in Detroit.
Incidentally, my uncle's camera captured my overdeveloped right arm muscle, as you can see. I suppose an 11-year-old boy would have been exercising his right hand quite a lot. Fortunately, the other arm compensated by becoming withered and puny. Everything balances up.
