This is hard. My father has been in hospice for over a year, and he is 500 miles away. Fortunately, my sister is in the same town as he is, and she sees him every day. We set up phone calls so that she can help him "hear" what we are talking about (he's rather deaf). We also have occasional family Zoom meetings on special days such as birthdays and holidays.

I go down there when I have extra days off such as my upcoming Thanksgiving break and Christmas break (helps to be a teacher with lengthier holiday breaks).
