Imagine walking into a cell phone store and noticing that all of the phones have the same kind of...odd wallpaper choice.
Camilla, who posted the pics to Twitter, told BuzzFeed Brasil that she was seated, having a coffee, when she saw this boy messing around with the cell phones and giggling.
According to Camilla, the boy would go up to the various cell phones displayed around the store, always with the same mischievous look on his face. "I saw him messing around and laughing, I hadn't seen him making faces," she said.
When Camilla got closer and realized what he had done, she laughed and congratulated the boy on his "work." Embarrassed, he just giggled and thanked her.
