No problem listening
Learning to express our anger appropriately is a good skill to develop. Often, when we are angry, we act out or strike out in hysteria or rage, and that does no one any good, and can be harmful, in fact.
I find when I sense anger that it helps, if the opportunity of the situation allows, to tell the person(s), " This is making me very angry." I use that on the phone when trying to work a problem of billing from a company.... keeping calm and polite with the person I'm talking to, but letting them know how really upset I am and having a difficult time with the stress of it all... I get better results and don't feel totally worked up and hating myself afterwards.
Learning if the anger is really related to the current situation, or if it's a reaction from something else we're carrying around is a good thing too!
Yeah, it's ok to get angry... at the right things and for the right reasons (even Jesus got angry, remember?) Good wishes in this...
