Nope...I don't think it can.
Actually, on the way home from the pumpkin patch I looked in the car lane next to us. A young girl was driving her sporty little car jamming to some music. She looked to be about 19 and was clearly enjoying her freedom. I remembered my care free days, and ever so briefly I thought "How nice to be her! I wish I had that freedom again!"
Then I looked behind me and saw Rebekah and Peter conked out in the car. I looked next to me and saw Ruth conked out in the car. I thought about how much joy the kids bring and how much I love them.
Sure - no responsibility is great. BUT only with responsibility do you get rewards. And I am very rewarded. I wouldn't trade my little life for anything. Well - not today. And not really for the past month. Come back and talk to me when I return to work in January. I might have a different tune then. ;-)
