“Go UP the stairs.  Slide DOWN the slide.  No, Sweetie.  Go UP the STAIRS.”  She could barely walk, but she was climbing up the slide.  Then, and now.  Spend ten minutes at a playground, and the appeal of climbing up the face of the slide is undeniable.  I am acutely aware of the dangers of falling off the slide, the risks of children bumping into each other. I vaguely remember falling off a slide, decades ago--one of the old, tall ones—before playgrounds had soft surfaces.  I like to see everyone going in the same direction.  Up the stairs.  Down the slide.  Nice, orderly, predictable, and safe.
