Worst - The hell my parents were put through as they sat through all my teenage committee meetings. To this day they still think I am inherently wicked. In fact, the elders made my dad a servant the day I moved out of the house.
Best - I never knew I could be such a wonderful person once I left.
Finding out that the people who taught me this maxim didn't give a shit about truth or logic but were focused on the growth and maintenance of the Watchtower.
