That is where a Belgian family went wrong last week, when they left their son on a bench next to their caravan.
The family had stopped at a French highway rest stop and set up their caravan for the night. When the young boy got too hot indoors, he decided to sleep outside on a bench.
When he woke the next morning, his family was gone, and he was on his own without any money or a phone. His family made the mistake of leaving the rest stop, without making sure their son was still with them.
The boy eventually made his way to a gas station where the police were contacted. His family was stopped about 200 miles away and immediately returned to the gas station to pick up their child.
