A major underlying issue in many quarrels is that people feel that someone else didn't treat them with the proper respect. The specific details of the quarrel are trivial compared to the fundamental need to be treated with respect.
"Who is an honorable person?" ask the Sages (Pirkei Avos 4:1). "The one who shows honor and respect to others." That is, your honor and respect does not depend on how others treat you. Rather, the more honor and respect that you express to others, the more honorable you yourself are. We all want to be treated with basic respect. And as we internalize the essential message of the Sages, we will decrease our concern about how others treat us and we will increase our concern about how we treat others.
