Hint: the name of this comes from the sound it makes
Hope you are having a good Monday so far. In case you were wondering, I didn't catch any mice yet. I've set up traps all around the house, but I haven't seen dead carcasses yet. I haven't even heard a squeak all morning. I'm not sure if this is a good thing. Either the mice died on their own or they decided to pack up and leave. I'll take either. But I think it's unlikely.
Here's the haiku hint for today's thingamajig:
always in a pair stuck together forever useless when apart
