question:  Why did Sauer and Flock yell so much?
context: He was a captain of guards in Estates-General Correctional Institution—better known to its inmates as the Jug—and if he hadn't been able to detect the scent of trouble brewing a cell-block away, he would never have survived to reach his captaincy. He had managed, by strength of will, not to hear that she had omitted to say "sir" every time she spoke to him, but he couldn't keep it up forever and he certainly couldn't overlook hysteria. From the born mechanic and the man with the gift of gab, society evolved to the point of smaller contact and less communication between the specializations, until now they could understand each other on only the most basic physical necessities—and not even always then. When you're in it, you don't much care what it is called; it is a place for punishment. Their names were Sauer and Flock. Sue-Ann Bradley heard them before she reached the Greensleeves. She was in a detachment of three unfortunates like herself, convoyed by an irritable guard, climbing the steel steps toward Block O from the floor below, when she heard the yelling. "Owoo-o-o," screamed Sauer from one end of the cell block and "Yow-w-w!" shrieked Flock at the other. The two guards turned to see what was coming in as the three new candidates for the Greensleeves slumped to a stop at the head of the stairs. "Here they are," Sodaro told them. The outside guard said sourly: "A woman, for God's sake. The outside guard pulled the switch that turned on the tanglefoot electronic fields that swamped the floor of the block corridor and of each individual cell. While the fields were on, you could ignore the prisoners—they simply could not move fast enough, against the electronic drag of the field, to do any harm.
