My Catholic School Girl mentality is engrained in me. I'm polite, I am hospitable, I recognize the appropriate way to behave in social situations, there's a different way to behave in Church at work, at a restaurant, as a guest in someones home, etc. But that doesn't mean I don't have many other colors.
I become enraged when I feel someone has taken advantage of someone in my family. I don't like confrontation for myself, but I won't back away from defending someone I love.
I've done it for my parents, my cousins, for aunts, for my sister, my friends... even people (including family) that really didn't even deserve or appreciate my help in the end. I try to control this part of me but it's something innate that causes me to throw my body in front of the person I'm defending and go toe to toe with the offender. But that's the most I would allow myself to step out of line.
Before law school I always tried to keep the peace, held my tongue, and was obedient. When I came out of law school I was an a**hole.
