A person with a transactional personality doesn’t respond in any way to situations… unless they have anything to gain. They’ll reach out or support only if you support them back. They’re the same in every circle of their life whether it’s personal, social, or professional. This is deeply rooted in their subconscious. However, since it isn't an entirely negative behavior, nobody takes note of it. You might notice this personality disorder more if they don’t react to negative situations like another person being bullied, abused, or killed.
