How to deal with this?

My house just got invaded by these neighbors that we know-but-don't-really-know, because they apparently locked themselves out of their house.

on perpendicular streets.

But yes, we don't know them at all. And I'm in high school. Their kids (the dad / kids are here) are in elementary school.

So yeah, nothing to say.

Plus I was napping in the room right next to the door, and I jumped up when the doorbell rang...
