Does your serenity, peace of mind, and joy depend upon a choice another person makes?
Think of your favorite person. They have good points and faults. You don’t have problems with their strengths, but when they won’t do something that’s important to you, you have a choice to make. One of your options is to resent them, become bitter, and/or dwell on the fact that there’s some little thing this person isn’t doing that you want them to do, and it can ruin your relationship.
