Lou Bou to I fully understand what you mean. It's a constant source of pain to me that I have no where to do this for a loved one. I used to think it was just for the mourner, that they have a special place to remember loved one's. But I plan to ensure my children have somewhere specific to leave flowers for me, and I find comfort in knowing that in a funny kind of way.
I don't find it pagan or foolish whatsoever. Like so many other things the WT denigrates, it's called being human.
