Give it a rest.
Nothing worse than being sanctimonious.
Everyone is individually special. What I do with my family at Christmas is none of your business.
As I’ve said elsewhere I wont be going to work then. If it is not safe for me to visit a non essential shop, or have a family member or friend over, then it cannot be safe to sit in an office. I work in public sector and can work from home, as much as employer wants people in the office.
