Funny thing happened on the way home from school today

I was sitting at a light, behind a white work van of some type as there were ladders and tools in the back. Just sitting there, getting ready to turn right when the light changed...then a man opened the passenger side door of the white van and spit a few times. Of course, I was like "oouuuhhh, gross". But then he began to vomit! And vomit. And vomit. Again I was like "gross!" but kept on watching. Then the light turned green. The van began to creep slowly forward but the man kept the door open and threw up some more. And I kept on watching. I slowly made my right turn but managed to see the van go straight with the man puking on the street. It did look like the van was going to turn into the Bickford's parking lot which I was thankful for. But then I was so intrigued with the fact that I was fixated on watching this person throw up repeatedly, from a moving van, even as I was making a turn. Why? It struck me as very odd to see this image at 3:30 on the afternoon on a weekday. I wouldn't be so surprised if it was at night or even on a weekend. So, then I began thinking of reasons why this man was sick. Was he starting his weekend really early? Did he and the boys have too many beers at lunch break? Or was he just sick with a stomach bug...
