This is the story of Jordan Adams. A 14-year-old boy who is the go-to babysitter for several families in a small community due to the fact that he is home-schooled and has done fairly well in his studies to the point he has plenty of spare time to watch the children of others. You don't get to play as Jordan though, rather you get to experience this story through the eyes of the children he babysits.
Jordan is a bit of a scrawny kid, but he gets good grades. While some of the other boys in his grade level may be a lot stronger than him, that is not to say he is a weakling. He has hit his pubescent growth spurt and is plenty capable of lifting a 10-year-old completely off the ground for piggy-backs or any form of rough play they might want to get into. Also, while being rather awkward with others his own age, he does very well and speaks quite eloquently with adults and relates quite well with children.
Now then, who is Jordan watching tonight?
Special note: In this story, you control the actions of Jordan, the majority of the decisions in the story are about Jordan's next action, and those that are not are about things that happened previously in time if you want to time-skip on a story-line's progress a little. However, making it a little strange, it is told from the 2nd person perspective of one of the children he is babysitting. (Just thought it would be interesting to see the subjective experiences of the child the MC is doing things with.)
