My senior year of high school, I flew to Atlanta for a scholarship interview. I hadn't slept the night before, we had an ice storm and I barely made my flight, I'd had nothing to eat and we circled ATL for almost an hour. All of this led to me losing it into the magazine I was reading (no time to get the pretty blue bag).
I was once on an extremely rough flight DEN-EAR on a prop plane where the entire (and I mean every single person) flight was using the baggies except me. The smell was awful and I buried my head into my coat to try to keep the smell at bay. I was never so happy to land.
