((Charlotte is your little sister's best friend. Don't worry she is only a year younger than you. She's very beautiful and attractive. But she is very shy and nervous around new people.))

Charlotte came over to have a sleepover with your little sister. When you go downstairs for a drink she was there also getting a drink. She spoke to you

"Hey, Your Ava's older brother right?"

she says sweetly and with a hint of shyness in her voice.
