Misunderstood anger

There are times when see someone get angry but what type of anger is it? Sometimes a person get angry out of frustration and sometimes they are angry at everything. I think one way to tell th type of anger is by the direction of the anger. If the anger is directed to a person without provocation the in my opinion they are angry at everything. If the anger is directed towards objects then I feel this is out frustration and a destructive way of handling anger. Essentially, this is a tantrum because something didn't go as they hoped. I'm guilty of behaving that way myself, I think we all have. It's an emotional immaturity because they lack the skills to handle their anger in a healthy productive way. Those constructive skill can be learned if an individual chooses to do so.
