How do you respond to kids who are really fresh and think they're cute/smart? I talk adolescents. There's no "rule" they're breaking that I can call them out on but they are a huge, distracting, work-avoiding nuisance. And they have perfected that innocent wise guy look: "Who me? I didn't do anything wrong. You're the one who made the mistake of saying something that could possibly be taken out of context." So far what I've tried that hasn't helped: Looking down at them with an expression of "seriously? Come on...," telling them that I fully expect them to use logic and context clues to derive my meaning, things like that. I know, nothing very powerful. I seriously don't know what to do with these guys. There is one main wise guy but he feeds off the snickers and follow up comments from the others. This is in the same difficult group I've posted about before but it's a different flavor of problem.
