Random happening of the day

I just went out to do a little grocery shopping for the week right? And I'm walking along and I;m about to pass what dad calls the "kmart" when i hear two kids call out "Robin-sensei, Robin sensei!" I turn and I see two little kids, maybe about 7 years old, about to dash out of the parking lot and cross the street to me, but there's a car coming! So I call out, "wait wait!!" in japanese, with my hand out and the kids stop just in time to not get hit by the car. (the car didn't see them until the last moment cause they're small and were about to come out from behind a parked car). Once the car passes I cross the street to them instead of hte other way around, and ask them what they're doing. They were shopping at the kmart (they each had a little bottle of juice and a snack). I asked where their mom was and they said she was working. So I'm like "okaaay two 7 year olds just out and about". So I'm about to leave and I notice they are follwing me, so I'm like "where are you going?" and they're like "to the grocery store!" (i had just told them thats where I was going), so they tag along with me, and i make a big show about looking before ways before i cross the street and such, and they 'help" me shop and all that, and as we're walking back I ask them where they are going now, and they said they hang out at the little arcade in the osada (kmart) until their mom gets off of work. So I drop them back off at the arcade on my way home, but I still notice that every now and then they'd pop out into the street to watch me walk away and wave. Finally I quickly turn a corner in hopes that if they can no longer see me they wont keep going out into the road lol.

They are not the only little kids I've seen wandering the streets without adult supervision here! People think their kids are so safe cause its japan, a small town, and a little island, and it just amazes me! Like even if there's not that big of a chance of them being abducted, they could still get hit by a car or something! Like they almost did trying to get to me. Makes me worried lol, like I could never imagine being allowed to roam the town, or just being dropped off at the arcade and told to wait when I was that young.
