Your behavipr was unacceptable no matter what your intentions or reasons were for doing it. Like with your parents trying to teach you acceptable behavior but you wouldnt listen or learn because you wanted to do ehat you wanted.....this is the same problem you had with yoyr supervisor.

She told you that yoyr behavior was unacceptable & even what you needed to stop doing but YOU CHOSE to not listen to her just like you chose NOT to listen to your parents. That is the foundation of your problem....doing what you want & not listening to the people who are telling you to stop behaviors that aren't acceltable.

You were doing that long before you graduated high school. The behavior is different but NOT LISTENING & doing ehat you are told is still the same.
