Old enough?

 When they were little and they would ask me if they could cut their own sandwich or walk across the street, or scrub the bathtub, I usually told them "When you are older."  This was my response to them in an effort to keep them safe. I didn't want them to cut themselves, get hit by a car, or get cleaner in their eyes or eat it, as little ones tend to do. Over time, I guess it became an automatic response for things like that. But the other day, HELLO LIGHTBULB. These kids ain't tiny anymore! And, believe it or not, they WANTED to scrub the tub.  I could get use to this.
