We have a monthly rotation with the girls. The Errand Girl, or EG, is the one who gets to buy gas, clear and set the table, help prep meals, ride in front when one of the parents is absent, push the cart at Wallies, select the type of cereals we eat and many other neat things. This mom a lot because anytime a situation arises when someone needs to get chosen I just pick the EG. She also gets served last as she's serving others. It's working out beautifully and we've been doing this for about 8 months! There's a peek into how we organize some of our lives, now if I could only be so consistent with the rest of my life!
