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

### Instruction:
In a library, three friends - Emma, Olivia, and Liam - are studying together. Emma brings a blue pen, Olivia brings a red pen, and Liam brings a green pen. They each leave their pens on the table when they go to find books. A librarian comes by and collects the pens, putting them in a drawer at the front desk. Afterward, another student returns a lost black pen to the same drawer. When the friends return, which color pen will each friend look for, and where will they expect to find it?

Respond very briefly.

Emma will look for a blue pen, Olivia will look for a red pen, and Liam will look for a green pen because those are the colors of the pens they brought with them. They will expect to find their pens in the drawer at the front desk where the librarian collected them, although they may not initially know that this is where the pens were placed. Upon realizing that their pens are not on the table where they left them, they would likely ask the librarian or a staff member and then be directed to the drawer. The black pen that was returned by another student is not relevant to what Emma, Olivia, and Liam are looking for.
