79 DAYS...

[Duchess]

She cries the loudest when she doesnt' get her way. It isn't usually like this. Nothing is usual anymore, except for her doing what she wants.
Mom is retired, I am working intermittently and she is working and has 4 days off, my other sister works and has the week off. (It is her cabin by the way) 
The asshole sister doesn't really understand that mom doesnt' travel well and won't be going to stay overnight. I can drive mom out there for the day, but that just doesn't make sense to me.
Its a "cabin" but it sleeps 6 with an extra blow up mattress.

Holy moly, cries the loudest. Well alrighty then. Have you made a decision?

Given what I know about your heart, I don't think it would be a fun time for you, you would be thinking about your mom alone on Christmas.
