Gratitude is something that most people appreciate as they go about their daily lives. However, although most parents would like to feel some gratitude from their children for the things we do, this shouldn't be the reason why we have and raise children. Parents will often run around wondering and complaining why children aren't more grateful for our providing the daily necessities of life, but you'll always feel somewhat cheated if you expect life to be fair and children to thank you for paying the electric bill or for putting gas in the car to take them here and there.
Someday, they might thank us, but I'm not waiting around for that to happen. I love my kids whether they recognize my efforts or not, believing that as they mature, gratitude will take root in their lives.
