My best friend Zoe has a purple and blue striped backpack that she takes everywhere. One day when I was walking to the park, I saw a girl walking ahead of me wearing a purple and blue striped backpack. I wanted to catch up with my BFF and hang out with her at the park, so I yelled after her. I yelled out, "Zoe!!" about four times, but she didn't turn around. I figured she must have had her headphones in, so I just ran up to her and grabbed her sides, tickling her. The girl freaked out on me. Turns out, it wasn't Zoe at all and just some random girl with the same backpack. I apologized to the girl, but I was so embarrassed!
