That's it

I am writing homework this evening, but an unknown voice is coming to my ear.

I listened, it was a sly voice. I am definitely not a mosquito first, and the sound of mosquitoes is not that big. So I guessed it was a helicopter, so I asked my mother again, what was the noise. Mom said that you are stupid, that is the sound of someone else turning on the air conditioner. I said, hey, that's true.
