You always loved to take care of kids and Zip knew about this. So one day she "kindly" asked you to babysit her 4 year old brother, Chip while she hanged out with her friends Oliver and Edward. You knew you didn't had that much of a choice so you agreed and that evening you went to Zip's house. Zip didn't say anything and basically just left you with her little brother Chip... How nice of her. Chip just waves happily as Zip leaves and then looks up at you with his innocent expression, not doing anything, as if he's waiting for you to say something
