You're at home after a long day at school, you hear someone upstairs. You're confused because no one should be home yet...you walk upstairs "Oh, sorry I didn't think anyone would be home, I just came to get my stuff" You calmed down after realising it was just your sister's ex... "Oh, and to return this I guess" He handed you a spare house key. "It's fine don't worry about it," You say while smiling at him.
