How assertive are you?
Some people are very assertive. These are people who aren't afraid to share their own opinions with people, even if they differ, and they also aren't afraid to speak up when something is bothering them.
And some people are total pushovers. These are people who are easily taken advantage of, and they usually don't speak up if something is bothering them, and they don't like sharing their opinions. And then some people are in between.
