I see what you&#x27;re getting at, but in this case it&#x27;s not really describing the state of mind. My behavior could be anxious without actually being anxious. For example shaking your leg is an anxious behavior, being jumpy or twitchy as well, but they don&#x27;t necessarily mean that the person behaving that way is anxious.<p>Anxious is describing the behavior itself, not the cause of it. You would be correct if it had said the behavior was due to being anxious, because that&#x27;s describing the mind state of who&#x27;s performing the behavior and the cause of it.
