I saw a little one walking down the sidewalk one day in the cold as well. He was about 2 and just had on a diaper and shirt. It was a very small town, so I went up to a the nearest house to see if they knew him. Sure enough thats where he came from. It was an old victorian style house, they were remodeling, so while Dad was painting the bathroom, little stinker got a paint can, pulled it to the door and undid the lock, out he went. Needless to say, they installed chains at the top of the door. Dad was so thankful, scared him half to death.
