Remembering people who have died

As we know, many people have died during the COVID crisis, and I wondered how their families will commemorate them.
My DGCs grandfather on the other side died 5 years ago, but the children, now 15 and 12, instigated a Pete/Grandad Memorial Day when they have chips for lunch and iced fancy cakes in the afternoon while watching horse racing on TV. I think it’s very fitting - any other ideas?
