When in doubt, talk. When in doubt, communicate.Talk, talk, talk until the problem resolves.

Una dintre consecintele lipsei de comunicare este auto-dezvaluirea (self-disclosure).

Lack of communication could contribute to some negative effects to those involved, due to several causes/effect. The causes could be many: an inability to communicate; not being in touch with one's own feelings; feeling too vulnerable or ashamed to express one's feelings (afraid of giving another that power over them), etc.

The effect is that the individuals feel distanced from and wary of each other. There's a growing lack of trust and greater resentment. Each person's self-esteem might diminish because of it. Round robin arguments may ensue. Anger, hurt and sadness all around for everyone.

The lack of respect will always be the cause for incomunication. This leads to people who will sit on their thoughts and let things go the way they do and even after the effect has gone sometimes still keep to themselves because they don't feel there is any sense to trying to say anything.

 "So that is the basic lesson that anybody learns in this universe. They learn to keep their mouth shut, and it’s the wrong lesson. When in doubt, talk. When in doubt, communicate." — L. Ron Hubbard

Whenever you have doubts about something, COMMUNICATE! Talk, talk, talk until the problem resolves. When you feel stress, disagreement or resistance between you and someone near you, the wrong thing to do is ignore the problem. Instead, start communicating.

When you know you should say something, say it! Take the bull by the horns. Move ahead in life. Spit it out. If you’re worried about the consequences of saying something, you can ask first.

Examples: "Lisa, I want to say something about your driving to help keep you out of accidents, but I don’t want to upset you. Can I tell you what I think or should I keep my mouth shut?"

 "Boss, should I tell you if I think you are giving me bad advice?"
"John, our marriage means so much to me I don’t want to say anything that would jeopardize it. But I have done something wrong and I’m sorry I did it. I think it would be good for our relationship if I told you. Don’t you think it’s best if we are 100% honest with each other?"

 "Can you listen to something unfortunate I have to say and remain calm? Are you ready?"

 In the long run, you are always better off by communicating. Take responsibility and talk. Staying silent solves nothing.
