Bad Parents or just plain stupid?

I think this is a combination of both bad parenting and plain stupidity. It's outright stupidity for adults to drink to stupor. Wisdom demands we have a limit to whatever we take in. How can the two parents be so stupid to get so drunk that they became unconscious outdoors.

To make the matter further worse they ask a barely 11 years old child to drive them home, risking their lives. Legally is that age not too young to drive. That is another very bad case of poor parenting
