That's my friend's name, mom??

It was an occasion that made me laughed out loud.

My family and I were watching a movie in my house, it was "City of Ember". I have a cat, named Rizky. Then, my mom called her, " Rizky Aulia, come here!!". It's my classmate's name!! So, I said, "Mom! It's my friend's name! She's a smart and cute girl!!". Then, all people laughed. How could my mom called a cat with a human's name?? So weird..
