As kids, we often learned things the hard way.
For example, when I was a little girl, I was forbidden from using knives. I was supposed to ask for an adult’s help instead. I didn’t listen to my parents and when they weren’t looking, used one anyway to cut a few slices of cheese to snack on. I ended up slicing my palm open. Like me, this little boy also learned a painful lesson.
While he probably wasn’t injured at all, I doubt he’ll forget why it’s not a good idea to go head first down a slide.
