Your husband's parents lives out of state and your family lives in state. You see your dad all the time because he lives in town so for the holidays you go to see your mom.
Except this year your MIL is in town. Your MIL would like to spend the night at your house on Christmas Eve so that she can see your children open their Christmas gifts. But that would mean NOT spending the holiday like you normally do with your mom. So what would you do?
Do you cancel with your Mom because you can see her any time (she's just an hour away) and she's spent every other Christmas with you so far and let MIL see your kids?
Or are you a B and decide to go see your Mom and plan a "fake Christmas" with the MIL?
