Stars in the Sky
A friend’s mother died, in commemoration, the family found a program where you pay money to officially name a bona fide star in the sky. They named one after their mom. I found a little, battery-operated star and sent it to them the next Christmas (a few months after her death). They told me they left it on, blinking, all of Christmas Eve and Christmas Day, and that it was helpful to see it as they were missing her, plus helpful to have a sense that others were thinking of them.
