They need to learn that responsibility and work are just a part of life. They enjoy a home where they are fed, clothed, and sheltered. Part of that privilege is contributing to the upkeep of the place where they live. Now, there will be times when they forget or choose to do other things instead of doing their jobs. It is always counter-productive to get angry.
Anger absolutely destroys the happiness of a child.
Although we don't mean to do it, when we get irritated and nag a child, he cannot feel loved, and love is the most important thing we can give a child, even more important than teaching responsibility. Anger only shows a lack of maturity and love on your part. And you certainly don't want to do their jobs for them, which teaches them to be irresponsible. You simply repeat your instructions to them, calmly and lovingly. Because it will fail, on many occasions.
