The last international flight I was on, some kid screamed for the entire 8 hours. I was seated in the back of the plane and the baby was up front, it was one of those Airbus 380's, and the screams filled the entire plane.
Two weeks later, as I was returning to Philly, who would be in the same car as me, but that very same family. I looked at my mom and felt like crying. Luckily the little girl got the chickenpox and had to stay with her grandparents.
