I live in a very middle class neighborhood in a relatively small town. 2000 sq ft houses on 0.2 acre lots, fences to keep the deer out, decent lawns, etc. Lots of mini-vans around, streets with speed limit of 25mph, etc. I think you get the idea.
I was driving down one of these quiet streets and just before I turned the corner I noticed a lady pushing a stroller in the opposite direction. The stroller looked to have an occupant, based on how hard she was pushing (it was uphill, she was really leaning into it, walking on her toes). She turned the corner and was heading the direction I was coming from. After I turned the corner she was no longer in view and about 200 yards down the road I see a young kid, probably no older then 2.5, standing against a telephone pole. I slowed down on the off chance he darted into the street and looked around for an adult. I didn’t see one. I looked for any signs of other kids around and found none. I pulled over about 50 yards beyond him and watched in my rear-view mirror for any signs of adults/older kids for the kid to rejoin. He dawdled there for about 30 seconds (could have been more, it was hard to tell) and I saw him take off away from me. I noticed one of the houses he was approaching had an open garage door and I hoped he would head into the open garage, but no luck. He ran past it. He looked very much alone to me.
What would you do at that point?
I was getting ready to turn around and follow him at a distance. I would not have approached the kid but I figured I needed to at least keep an eye on him. Just as I was about to start my turn I noticed the lady with the stroller appear around the corner again and gesture to the kid. He looked like he responded so I just went on my way.
