I'm getting angry
Is there a reason why you are angry?
I am angry that someone asked me to do something ridiculous.
Sometimes people get angry and that's normal. If you think that you're getting angry you might want to try and walk away to cool off.
I think you're right. It's not good to make a habit of hair-trigger reactions.
Waiting just a few seconds between the moment you became angry and the the response can make all the difference. Most of the people in prison for violent crimes say if they'd counted to five before lashing out in anger, they'd be free instead of serving a multi-year sentence.
