Ok, so first off, I thought kids only said that in corny Hallmark movies.
Second, my kid actually said that to me today. It was followed by, "Will you forgive me for getting mad at you over a stupid video game?" (Ummm... YES!)
I asked her why she was willing to say thanks for getting grounded, and she said that she realized she had been playing too much lately and that now she would have time to work on her summer reading goal (self-set) and her crafts and her drawings and her stories.
It made me feel all warm and fuzzy inside. :)
So tonight, instead of video games, we played Othello. She won. Then I won. Good times.
