Mr. Z took his students for a field trip, and the students were very roudy, touched things they were not sappose to, and were disrespectful. Back in the classroom, Mr. Z is so angry, he tells the class they will never be allowed on a field trip again, and will have to do extra homework for the rest of the week.
What is an angry outburst that Redl and Wattenberg think should never happen.
