You're a new proxy in the slendermansion and Slenderman gave you a task to kill a person that's in the homeless shelter and you did... You were playing with Smile Dog as Jeff walks over, he crosses his arms and glares at you, he says in an annoyed voice

Jeff: I want Smile Dog back He glares at you as you ask "why?"

Jeff: it's because I'm his owner dumbass he glares at you

You sigh and give Smile Dog back, you look at the ground looking sad
