Wow, I never considered the sitters we used for occasional evenings away from the kids to be strangers! They were competent responsible teenagers with younger siblings. They knew how to take care of my kids and the kids loved them to come over and have fun and give them snacks before the kids went to bed. My kids are grown now but I still keep in touch with these grownup sitters. They are fine young women and my kids & we were privileged to have them in our home.
