I planned to have a Christmas party (boat parade viewing and ornament crafting) at my home this upcoming Saturday but my household has come down with some kind of illness. I want to cancel it but my family says I’m being selfish because people might want to use my house to view the boat parade, saying I should offer to let them be in my back yard while my sick family members (myself, husband, and younger child) stay inside. What would be a responsible course of action here?
