Of course. If someone wants to be angry, that's their choice.

Yet a lot of people get angry easily, and being an easily-triggered person works against a person's life. No one wants to constantly have to walk on eggshells around another person in order to be their friend, partner, child, etc.

Personally, I don't enjoy the emotion of being angry. If you do, more power to you.

It's nice to be able to afford to not get angry. That's not an option for everyone.

With respect, it's not a matter of money or resources.

Getting angry is optional. With some practice (largely, mindfulness) people can learn to notice their emotions and not become strongly identified with whatever is happening in the moment, and choose to do something more productive than simply stewing or ruminating in the unfairness of life.

Thanks for engaging.
