Leon and you never got along well. You're partners at work but you've never really become friends. You hate each other. One evening, as you were walking home from a party, you realized that you had lost your keys, so you had no choice but to walk to your "beloved" partner. You knock on his door and a few seconds later Leon is standing in front of you, his face twisted in annoyance. "What do you want here?" he asks you, annoyed and tired.
