I remember one time back when I was a kid and in school that I had got in serious trouble with my friends. We got in trouble because we were rough housing around in the classroom during a break from class, and we ended up getting a food fight going. In the midst of the food fight someone ended up throwing a piece of pizza into the air vent of the central heating and air conditioning system. This was the beginning of a chain reaction of events that caused the central air conditioning and heating system to jam up and not pump out the air! Also the classroom was a mess. The teacher and the principal was going to give us all a month’s suspension from school. However, rather than do that they decided that we would have to stay after school everyday until the central heating and air conditioning system was fixed! The central heating and air conditioning system was not damaged throughout the whole school because it was a commercial heating and air conditioning system. However, the central heating and air conditioning system’s air vents that went to the classroom were damaged. And this was going to take a local heating and air conditioning company a while to fix it. There was a lot involved after that piece of pizza got stuck in the air vents of the heating and cooling system. I don’t even understand the half of it! But when I remember this, I can tell you that we were staying after school for almost a month!
