Why is it, or why isn't it, appropriate to share one's opinion with others?

       There are times when it is important for you to share your opinions with others, and there are times when it is better if you keep your opinions to yourself. If you are working in a group on a project, either for work or for school, it is important that you voice your opinion so that the project contains some of your ideas. Also, if someone asks for your opinion on something, as long as the answer isn't going to hurt their feelings, you should give them your honest opinion.
       On the other hand, if your opinion is going to hurt someone's feelings, it is better if you keep it to yourself. I'm not saying that you should lie to the person who is asking, but you should find some answer that is both truthfull and doesn't hurt their feelings. Also, if you are very opinionated on some really heated topics, unless you want to get in trouble at school, work, or even with the government depending on what the topic is, you should probably keep it to yourself.
