It is nice to see how other teachers manage the same problems.  When we are put in similar situations, it is sometimes the abilitty to handle difficult people and difficult situations that shows our strength as a person, and is the greatest teaching tool that we may have.  Students will actually mimic your behaviors, and if you set the bar high and hold to your moral and ethical stance... you may not be everyone's favorite teacher, but you will be giving each student a good life skill while sharing the information on your class topic.
