How many red cars that look just like his mom’s are just sitting there empty and unlocked at any given time?
He has a history of hiding in other peoples cars? How does that even happen more than once?
Four-year-old children should not be wondering about outside of the home without an adult. Was he at the neighbors house for an arranged play date or did he just roam free in the neighborhood?
I agree that the neighbor should never have just told this little boy old to go home. Any responsible adult, finding a four-year-old on their porch that doesn’t belong here, will take the child by the hand and walk them the parents door, hoping that the parent will be shocked to see that the child was outside wandering around and do a better job of supervising them in the future.
