mother of the year

We were parked next to this lady and her 3 sons, all boys, aged 2, 4 and 6.  Every day she piled them up and took them....?....then came home at dinner time every night.  She went inside and the kids stayed out for hours on end.  One day, they must have been feeling really daring as the oldest one shimmied up the ladder on the back of the camper, followed by the 4 year old.  Upon reaching the roof, the 6 year old squealed with delight and leaped off the roof of the camper like a boss. As the 4 year old climbed the ladder he yelled "wait, wait for me!" He made it up and flew off.  I though "Oh my God, where is that baby in dipes?" and sure enough, he was ascending the ladder going to follow his brothers! I about had a massive M.I. and John zoomed over next door, banged on the door and Mom eventually opened the door. He said "Lady! Your toddler it on the roof about to jump off!" She could have cared less.  She slowly sashayed over and had her oldest climb back up the ladder and help the toddler down.  We didn't take our eyes off them ever again.
