Well how did this happen

Today I felt like I was asleep until about 4:00 pm and yes I did go to school. It was really boring and kind of a slump. When I was on my way to class I fell asleep the moment I got in the seat. After about fifteen minutes of being on the highway I woke up at a traffic light and I was suprised to see were I was. I was at the Lake Norman school. All I could say was Well how did this happen.
