Bullshit.
It's his own damned private property, why can't he be naked?
That's like being arrested for not paying to sleep on your own bed, it's not a fuckin' hotel, it's YOUR OWN DAMN PROPERTY.
Plus, the fuck was a woman and a 7 year old doing outside when it was still dark?
Why would the kid care anyway, if it's a boy, you'd think it'd come as no surprise to see a penis, but no. Even if it was a girl, you'd think they'd figure out that there's a difference between a girl, and a guy.
I mean, if I was a girl, and I saw that, I'd be like "Oh, so that's why they're called something else.!"
