Picture the scene

I'm standing at the fridge, and I hear a familiar meow, strangely distant.

Oh no, did he go out the window!? No, I've not seen him by the window
at all, and it sounds like it's coming from the entryway.

Is he trapped in the washing machine closet? No, it's completely
closed and hasn't been opened all day.

Wait a minute, the front door is ajar!

I run out into the hallway, and see our little furry friend crying to
be let into the apartment next door. I scoop him up and take him back
home, locking the door behind me
