"I was at home all afternoon with my girlfriend. We went out around 6:30pm, and had a couple of beers. After the beers, we went home. It was around 8:30 then. I was so tired I slept straight away. I woke up much later -- at about 9:45, with an aggravating headache, which got worse with the drilling they were doing outside. You see, I live near a motel. The noise was so aggravating me that I fell asleep again. Donno much what happened after that."
