Have you tried the roller coaster yet? Your drawing is dizzily accurate!
I went on one once with a friend whose parents drove us to the fair. It was a long, winding car ride during the high heat of summer, and I felt a bit sick even before we arrived at the fair. Plus, they fed us a boxed lunch on the way, which was grape juice (it was warm) and an egg salad sandwich (plenty of mayonnaise). I did not care for either, but I politely tried my best. By the time I got on the roller coaster, I was feeling green.
I did manage to go all the way around before I threw up. To this day, I can’t drink grape juice or eat an egg salad sandwich. Still, whenever I have to write about a character who is not feeling well, I can recall precisely that feeling so as to include accurate details.
