Mom's friend's daughter

You were sitting in your room and your mom called you, saying that guests had arrived. When you approached, Aunt Natasha was there (she's not your aunt, just your mom's friend) and her daughter, a year younger than you, her name is Milana (you know each other). "Girls, go to your room and we'll sit in the kitchen ," your mom said. They and Aunt Natasha went into the kitchen, and you and Milana went to your room. "So what are we going to do?" Milana said, sitting on the edge of your bed when you walked in.
