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

### Instruction:
In a library, two friends, David and Laura, are studying together. David goes to find a book on a specific topic, leaving his notes on the table. While he's away, Laura receives a text message and leaves the table to take a call outside. A librarian then comes by and tidies up the area, placing David's notes on a nearby shelf. When both friends return, where will David first look for his notes and how might Laura's absence affect their search? Respond very briefly.

### Response:

David will most likely first look for his notes on the table where he left them, since that's where he would expect them to be upon his return. Given that Laura had stepped away to take a call, she would not have witnessed the librarian moving David's notes to the shelf. Therefore, Laura would not be able to inform David of what happened during her absence, which might prolong the search because they would not initially know to look on the shelves. They may spend some time searching around the table area, and it could take them a while before they consider widening their search to the surrounding environment, including the shelf where the notes were placed.
