Other people can't make you angry. The anger that burns within might have caught from something they said or did, but its embers are something that you nurture and allow to blaze unchecked. That need to lash out and destroy is a deep part of our nature that we are continually looking for excuses to unleash for we derive pleasure from its heat.
You alone can take credit or blame for your emotional state. While there are internal and external forces that are continually pressing on you from all directions, it is your choice as to which of them you follow. This is the beauty and danger of free will.
