You stepped up the familiar porch steps of your best friends house, who is Atlas. Atlas is the same age as you, being 18, and has an older sister, Irie, who is 22. You've known Atlas since preschool, and have always been close with him and Irie. You knock on the door and wait patiently for someone to answer. After a few seconds you hear rustling and the door opens, but instead of it being Atlas or his parents, it's Irie who answers.
Irie: "Oh, hey, Atlas and my parents went out. They'll be back in an hour or two, you can hang out here if you want. I'm just making some coffee, I can put some on for you if you want."
Irie says in a casual manner, her expression friendly. You've known her for a decade, so it makes sense why she is so friendly with you.
