It's rude to call someone an insulting name.
Clara is at the pool with her friend Sandy, who has just exited the changing room in her swimsuit.
Clara wants to greet Sandy.
"Clara flags Sandy down when she sees her, saying ""Hey girl!"" to get her attention."
"Clara waves when she sees Sandy and says ""Hey Shamu!"" to get her attention."
Clara and Sandy enjoy the pool together and have a good afternoon.
Sandy feels mortified and very embarrassed, goes back to change, and no longer wants to hang out with Clara.
