When I was finished with my doctor’s appointment, I made my way to the lobby. My mom was going to pick me up, but knowing how she was always late, I realized I had some time to spare. I took a seat in the lobby and smiled politely at the three elderly people sitting near me. There were two women and an old man. Then, I dug into my backpack for my library book.

Soon, one of the women and the man left. It was just me and the beautiful gray- haired woman in the lobby.

Why did the narrator look in her backpack for her library book?
