Must Have Been The Wind

So I took the elevator to the second floor
Walked down the hall and then I knocked upon her door
She opened up and I asked about the things I've been hearing
She said, "I think your ears are playing tricks on you"
Sweater zipped up to her chin
"Thanks for caring, sir, that's nice of you, but I have to go back in. Wish I could tell you about the noise, but I didn't hear a thing"
She said, "It must have been the wind, it must have been the wind. Must have been the wind, it must have been the wind"
