She just invited us over for Christmas
The details are everything. From what time-to-what time?Go for no longer than 1.5 - 2 hrs, and let her know ahead
of time when you will be there. Is this a sit down meal? Then NO. You don't want to be caught waiting around for the meal
to be ready. Come for dessert instead. Try to avoid cocktail hour. Always have an escape plan. Do not discuss the "whys"
with the kids - not yet if you're giving this relationship a chance. Go at Christmas only if you are not sacrificing some substantial
plans for your own family elsewhere. When in doubt - yes, you have a good idea for doing it another time. Some of the same
recommendations still apply, and best to meet on neutral turf with your own transportation to leave.
