This is from the readers point of view. You don't know where you came from. You don't know where you've been. You don't even recognise yourself. You're lying in the street whilst it's pouring it down. Your hurt and alone. Your clothes are in even worse condition than you are. You feel that your going to die there. Until a short, joking skeleton named Sans, Invites you to come and live with him, and his brothers.
