I know many who don't mark the day a loved one died in any way and I guess that's their choice, we're all different and deal with these things in various ways for that reason. I'm not one to create a shrine to people I've lost, nor do I have to go to gravesites or memorial walls to feel closer to them, although I certainly remember them well and fondly, their lives I mean, not their deaths.
I hope you're well and have had a good couple days.
