If you have an issue, just talk about it. It is better than the alternative – being bitter, not knowing if you are wrong or letting things as they are if you are right.
Talking is part of thinking. If you do not talk about issues, you cannot really think. Other people are extensions of your brain that you do not posses. They know stuff you do not know.
Not talking about what you think will over time literary drive you insane or at least deeply unhappy.
Someone lauging or being mad because of someting you say in short term is much better to being bitter and being affraid in the long term.
