PUM! What happened?

    We were at the bus just starting to drive through Corredor Sur. Everybody was sleeping or concentrated in their Blackberry, Homework, iPod or Nintendo. It was calmed and everybody was enjoying the ride until we heard a PUM!! Ricky (Maria Fernanda's brother) said he thought that the roof was going to fall -.- . The right side of the bus started like jumping, and smoke was going out of the wheel. The bus stopped. Everybody jumped off of their sits laughing, and at the same time scared. (I know it's weird that people laugh when they are scared, but well what can we do about it.) All of us started to look at the windows at the right to see what had happened. It was that the bus wheel was flat. The bus had no air conditioner and we started going again. We were on the right path so, we couldn't go to the left side. (at that time not even one car will let us pass) We went through the right path until we finally got to Atlapa. In Atlapa, Daniel, the bus's driver, started changing the wheel. The sun was shining, and all of us where out of the bus. It was a very hot day, and I had allergy in my face. The sun and the climate didn't help with my allergy, so it got worst. I had to wait like 15 minutes outside while Daniel changed the wheel. We arrived to school at 9:00 am, and I arrived with my face all red.
