To what extent do you believe people make you React a certain way?

I believe that people don't Make one react a certain way. But I do believe that Someone may know a person well enough to know how they will react to something. It is up to the person reacting to decide whether they should give the antagonist the reaction they are looking for.

I also believe that showing a reaction to something is a sign of weakness. You show the antagonist that they have power over you. That they are able to get to you so you can react the way they want you to. Depending on the reaction, they probably are trying to get you in trouble. In most cases, negative reactions turn out to be aggressive and violent.

So, no. I don't believe that people can make a definite reaction out of someone. But I do believe they can know what buttons to push to try. It's just a matter of self control.

When people annoy me or get me mad.
