2015, the end.

We had Steve through December 30th.  He wanted to know why he couldn't stay longer that morning.  It is difficult at best to try and tell him why without upsetting him so I opted for telling him he could stay forever.

Steve:  I can?
Me:  Sure!
Steve:  When do I start?
Me:  Now!
Steve:  Now?
Me:  Yup!
Steve:  Oh, good.  Can I go to bed now?
Me:  Bwwwaaaa, I don't think so.
