Be sure YOU are also taking care of Yourself. Have a few family/friends "putter about" the house with you as well. Nothing fancy/elaborate. Just sharing some everyday normal stuff. It helps. It is too easy to seek isolation in times like this. You may not have been very close, but a connection was still made. So that whole "grieving" cycle still needs to be gone through.
As I said before, sometimes just that presence of another person nearby means more than idle/awkward conversation. Plus watch out for overindulgence on the inevitable food that gets dropped off. Some is good and a comfort, but ...
And be careful in this weather! I don't know how yours is right now, but I had -33 last night and -25 the night before! (Farenheit of course) It got up to near Zero this afternoon. And they are now predicting low 20's with snow and possibly freezing rain tomorrow! Near record cold to another Ice Storm in 24 hours! Winter! Rah rah.

p.s. My one uncle found a "friend" after my aunt passed on. She was always referred to as "and special friend" or by her first name. And their kids just referred to her by first name - except for a couple who could not get past the idea of someone else besides their mother being with their father. After he passed on, they were a little sorry for their views.
