How Do They Do It?

You've probably heard about how so many grandparents are raising their grandchildren. I really, really admire them! We had three grandkids here for two days and one night, ages 5-10. These are very good kids; obedient, fun, polite. But I was e-x-h-a-u-s-t-e-d when they left. How do grandparents do it when the kids are tough to handle and unruly?? Have I gotten soft and lazy? Maybe if I had them all the time I would eventually get in the groove and not be so tired out. One at a time is a piece of cake .... but three at once is like running a marathon. I think I'll sleep good tonight.
