Wow, yes, that really does make a lot of sense to me. I still don't understand laying flowers or visiting a loved ones grave. We didn't do that when I was growing up, and it didn't matter who died. Even when my father passed away when I was in my teens, we never went back to visit his grave.
I think I've spent most of my adult life trying to figure out what was normal and what wasn't. It was especially hard when raising my own children, as I wanted to provide a more standard childhood for them...but I didn't know how the heck to do that. I actually copied a lot of the mothers, whose parenting skills and traditions I admired.
I hope my dear children never figure out that the traditions we hold so close were mostly a copy of someone elses or something I pulled out of thin air.
