Have you ever become the very person you used to judge and criticize?
Maybe you used to sit back and judge a parent with a screaming child and now your child is the one screaming. Or, was negative about gay people and now your own child is gay. Maybe you used to judge people who got divorced and now you are getting one. Could be anything, anything you judged or felt you would never do, and now find yourself in the very position you never thought you would be in.
When you found yourself in that place, were you hard on yourself? What was your thought process?
