I want my family to watch the twins while my wife, daughter and I cut down our christmass tree
Why can't you all do it together?
My family is not happy with my decision to cut down on Christmas expenses
You shouldn't keep your parents and twins from doing something special like cutting a tree for Christmas. Do it as a family and it will be more special.
I just don't want my twins there, okay?
You are wrong about this. Special events like these should be attended by the whole family.
