very rarely....because nobody talks to me anymore after the last tirade - jk.
I don't react much - being pretty tolerant, there isn't much to criticize. If I was mean to someone that's the only time i'd regret.
On the flip side, when I worked, I often would take on challenges that I'd regret because it meant less time with family.
How often do you have a conversation without distractions or interruptions ?
