The playground that ought to be empty

Walking along a playground, I see many children wandering around. Some others are standing. Some are just watching. Some stopped with whatever they were doing and just keep staring at me. Some waved. Some others simply smiled and I responded the same way to those.

Questions...many of them then started to fly like arrows. "Why" was the most popular one. I don't know the answer as to why the "why's." I stopped for a bit to ponder upon the questions that targeted me. "Come along now, my child." Papa said to me. "Who are these children" I asked Papa, "and where are their parents?" Papa just responded with a smile. Then I asked one more question which stopped Papa: "Are they here because they've been naughty?" Papa turned around, crouched in front of me and said: "No, my child. They're here for a reason. They're sick." "Why are they sick at this age?" I responded " They're so young. Did they do something bad? Then Papa paused & he smiled to comfort me. He said: "Come here" and hugged me. Then he whispered in my ear, "That's because God wants to show us how graceful and powerful He is."
