If someone regrets things they have done wrong in the past, it is forbidden to remind them of those past things. For example "You used to be so selfish/bitter/broigis. Its good to see you becoming more giving/happy..." or "you sure spend a lot of time studying Torah. There was a time when no one could get you to lift a book to learn" or "don't think you are so great because you've been behaving so highly in seminary/yeshiva. I remember you way back when... you used to be so wild. people don't just change"

Lesson 2
