Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
Mr. Johnson is a teacher who has a collection of 20 books on his desk. He leaves the classroom for lunch and asks Tom, one of his students, to organize the books by color while he's gone. Tom sorts the books into four piles: red, blue, green, and yellow. After Tom finishes, another student, Alice, enters the room and decides to rearrange the books by size instead. When Mr. Johnson returns from lunch, he sees the books organized by size but doesn't know that Alice changed the arrangement. What does Mr. Johnson think about the way the books are sorted?
Provide a very brief response.

### Response:

Mr. Johnson, upon returning, might initially be confused since he expected the books to be sorted by color rather than by size. Once he notices that the books are arranged differently than he instructed, he may think that Tom misunderstood his directions, or he may believe that Tom had an alternative idea for organizing the books and went with sorting them by size instead. Mr. Johnson is not aware of Alice's involvement and therefore attributes the change to Tom. Depending on his personality and relationship with his students, he might inquire about the change or simply accept the new arrangement.
