I'm rarely angry though for me it boils down to problem solving. If I get annoyed by a colleague that I have to interact with I attempt to view the situation from the outside as a neutral observer. Unfounded assumptions often leads to conflicts and communication is key to understanding where and why someone drew the conclusions they did. Talking directly and frankly to people's faces is often necessary. If I can distill a number of win-win principles then that provides me with a neutral compass that is objectively useful.
