My replacement

Thomas started work a little later than usual today, which meant he had more time to spend with the parrots before work. After his shower, he went upstairs to change. I was changing the parrots' food and water downstairs. Rocky was following me around in a threatening manner, so I placed him on the stairs and told him to go up and find Thomas.

I finished with the cages and realized the two of them had been up there for quite a long time. As I mounted the stairs, I heard Rocky giggling. Entering my bedroom, I see Thomas on the bed and Rocky on my pillow!

I asked what was going on. Rocky just kept laughing. Thomas said, "Looks like you've been replaced!"
