Try to avoid mistaking the lowering of the brow alone as anger when it may be someone in a serious mood, thinking, or solving a puzzle etc. Take into account other potential signs of anger in the face, body language and environment. In my experience, someone being accused of being anger when they are not can in fact make them angry.
