Suspicious Sounds

I'd been in my room for about 30 minutes when I heard a noise.

A vibrating sound which seems to come through the wall from my neighbour. It sounds just like a drill.

It's lasted a few minutes now. Maybe it's the SiB people going around checking all the fire alarms. We've already had a little dooooaaa today.

Five minutes later it seems closer. Or maybe just louder.
What is it?

It's in my room. It's by my bed. It's inside my nightstand!

Wait a minute...

I open the bottom drawer and voila, there's a certain pink toy there which spontaneously turned itself on and started vibrating. Louder and louder.


This has got to mean something...
