Brother-in-Law's Kids Are Coming.

I am going to pick them up in a few minutes.  A little background.  He married into a ready made family.  She had a girl and a little boy when they met.  The girl still saw her dad every other weekend but the little boy's father didn't even know he existed.  My brother-in-law marries her and adopts the little boy as his own.  The little girl is sort of a pain and he really never could get along with her.  Fast forward several years and they are getting a divorce.  BIL is getting custody of son.  She didn't even put up a fight.  She just wanted her car and a tv.  I don't even have to tell you my feelings about her.  Well my wife invited his son to come and stay with us for the week.  Turns out his sister took that as an open invitation to come also.  Bil was coming up for a wedding but refuses to ride in the same car with the girl so the mother is driving them up to within an hour of where we live.  Of course I get to go get them because my wife has some sort of shower to go to today.  She also has class Thursday- Saturday so guess who gets to entertain four kids?  On top of it all my wife says our two boys can sleep downstairs this week so the other two can have a bed.  I'll be danged.  My 360 is down there and I wouldn't be able to play.  It's going to be a long week.
