Avoidance used to be my standard MO -- it's where I go first when I'm in conflict and not thinking and being mindful of my actions and feelings. Also, laughing off unacceptable behavior, like "Oh you!" when inside I'm thinking Oh, you awful, person! How I loathe you, let me count the ways!
Regrettably, I think about some of the times I avoided conflict to the detriment of myself and people I really liked/loved, and realize it made me kind of a ****ty friend.
