This morning, I heard a rustling sound coming from the wall in my room.
It seems like something has gotten into the hole for the old air conditioner.
At first, I thought it was a cockroach, but when I smacked the wall with a book, I heard a squeak like a small animal…
I looked it up online, and it seems highly likely to be a bat or a mouse.
I went out to the balcony to check, and found that the hole on the outside was left uncovered.
But it’s too dark to see anything.
I wonder what on earth it could be…
