How young is too young?

[Cutz]

Why not just leave the kid at the house and tell them not to go anywhere or open the door for anyone? That seems safer than leaving them alone at the park all day where some weirdo could abduct them.

Dude, have you ever tried to abduct some kid from a park? It's crazy hard! The mommy brigade is so protective, you can't even get out of your windowless van before they've called the cops. They don't care if you're talking to their kid or someone else's, they'll still get all up in yo grill. Playgrounds are like the safest place in the world.
