My parents were away for 2 weeks, and I was home alone with my brother. He himself was away 90% of the time as well. As a result I spend a lot of time on cooking, hoovering, doing the dishes and doing the laundry.
The most rebellous thing I did during those weeks was drink booze at an odd time. I just stood up around 9:30, went downstairs to get something to drink and grabbed some orange juice, which my dad would get pissed about already. Then I noticed a bottle of Malibu standing there next to the OJ. Well, bottoms up! Walked around all day with a nice buzz in my head.
I could also hook up my laptop to some speakers downstairs, and could listen to smooth jazz while lounging in the living room and read a book. So very relaxed that was.
