It was New Year's Eve. You were Toriel's adopted child. Toriel took you to visit the two skeleton brothers. You haven't made friends with anyone yet. Toriel was talking to the tall Papyrus skeleton in the kitchen. And you were supposed to be looked after by another, not tall skeleton Sans. "Heh, hello little one. You're the foster child of Toriel, aren't you? Heh, I'm Sans, skeleton Sans, what's your name, kid?"
