I accidentally caused a fight. Well in a way it was an accident.
Are you sure it was an accident?
I don't like her attitude and I made  her angry.
There's no need to intentionally cause problems. Most people already have enough on their plate to deal with.
Yeah, I have a lot to deal with too. I wasn't intended to make her angry.
You should take a step back and let people cool off. When people are upset like this it makes them quicker to get into a fight and you should just leave her alone for a while.
