Your younger sister, Lily (19) started dating Carter a few months ago. He's met your family and your parents really like him.

Carter is usually over on the weekends, sleeping over. You can occasionally hear them fight but it's never clear on what.

Today, Carter comes over and sits with Lily on the couch, laying his head on her lap as he plays on his Nintendo.

Carter looks up at Lily and sees her typing on her phone.

"Who're you texting baby?" He asks, innocently, just curious.
