Just going for a walk

Today I was on my way to the elementary to help out in the kids classes and on my way there I saw something that made me stop right there in the middle of the road.  I looked around to make sure what I was seeing was what I thought it was.  It was.

Happily walking down the middle of the road was a little boy I would say about 2 1/2 years old, sporting only his diaper, pushing a stroller.  By himself.  I looked around again to see if he had a parent somewhere nearby possibly distracted or frantically searching for him.  Nope.
So I pulled over and got out.  I walked up to him and we had a little conversation.

"Hi there"
"hi"
"What are you doing?"
"Just going for a walk"
"Where is your mom?"
          shrug....
"Do you know where your house is?"
         he looks around and points to a house nearby

At this point I'm thinking, oh this poor parent probably has no idea he is here, they will be beside themselves when they find out where he has been.  We walk up to the front door, which is closed tight (not the chosen escape route).  We park the stroller, and I ring the bell.  A man comes to the door on his cell phone.  I asked him if this was his child?  He looks down and rolls his eyes and confirms its his child.  I inform him that I found him down the road in the middle of the street.  He gives an annoyed look and sighs and then takes the kid inside. I think he mumbled thanks.

Now, I know that there are some very talented toddler escape artists in the world.  But they are often delivered back into the arms of frantic, embarrassed, shocked, scared, parents who cannot believe that their child has gone missing and up the road in less than two minutes.  I get this.  I didn't get this guy and it just made me sad.  I could have been a kidnapper who just scooped him up and drove away, or I could have not seen him and run him over, or he could have kept walking and gotten lost.  Too many possibilities to this scenario.
