Thanks howardblott! Junk food and alcohol sounds like a rich cultural in its own right :) but yes I think it takes much care to preserve these traditions, and I'm not sure if it will survive through the next generation.

Even 100 years ago, families might hold these ceremonies a few times a month to commemorate each ancestor for several generations back; now my family holds them several times a year, but that already feels like more than the average modern family has the time for.
