After 9 years of repeating same things over and over, Arabella finally decided to clean up after dinner for the whole familiy. I think the book of awesome had something to do with it. Since I told them to start writing their own book of awesome and record whatever they feel it's awesome. And I realized that she always tried to do something that would make us (the parents) happy, even though sometimes, she simply act rebellious! ( I guess, that must be some kind of bad gene from me.)
Even though she doesn't really clean after herself all the time, but I do notice that she does try to help out more often. helping out with little kids, doing art work with them, clean up after her mess if I am working etc.
Having children start to show sign of taking responsibility and behave in a way that you know they will grow up to be just fine! AWESOME!
