If you wonder why they sometimes lash out unexpectedly, that may be the reason. If you wonder why their punishment seems unjust or their attitude unfair, that may be the reason. A lot of parents feel unappreciated. It would do us all good to remember that once there was a time in life when one week of neglect would have killed us. If parents feel unappreciated, so do children.
Children feel their good points are overlooked and their bad points are magnified.
They feel that the spotlight is always turned on the times they do wrong and never on the times they do right. They think that they get the blame they deserve but never the credit that they deserve. The world is also filled with wives and husbands who feel unappreciated. In family life the fruit of our ingratitude is everywhere and bitter. If people only realized how much they are appreciated.
