For example, if you feel resentment about doing your teenager's laundry, teach them to do their own. This is the price you must pay for setting yourself free. Within a few months, they'll learn to separate their clothes correctly, and make sure they don't throw shrinkable clothes into the dryer. Learn to stand up for yourself in the face of anger. If people get angry with you, and give you pressure through anger or guilt, hold your ground.
Many people use anger, or the threat of anger, to control or manipulate their way through the world.
See the ploy, and don't give in, if you are being reasonable. Calmly and firmly hold your ground. The less you say, beyond what you are willing to do, the better for you and the relationship. I am not willing to pay for something you decided to buy without consulting me. Next time, please ask me first.
