When my niece needed a babysitter for her 4 daughters, I jumped at the chance. You see, traveling like I do, I really missed out on most of their lives but because they are ages 4, 6, 8 and 10, there is still time for me to catch some of that. I learned much and trying not to teach them like my Drill Instructor taught me was probably the hardest part. In the end when we all played together- I taught them each the art of making a paper airplane and how to fly them, learned that after taking their dinner orders, they all change before I could finish cooking it, we ran around and destroyed the house and even ended up with my hair done and finger nail polish on ( just one hand). I'd say it was pretty rewarding and not just for me but for them too, so much that we might just do it again real soon.
Here is a little video of the evening near the end
