Part of your duties, if you shall accept them, is to share stories about your parents and grandparents with your children. That way they can share stories with their children and so on, extending the legacy of your family.
The ones we love who pass away often live on through us. Can you remember doing something in a way that made you (or someone else) say that you acted like your mom or dad? Or even like one of your grandparents?
In those moments, you have the opportunity to share what your parents are / were like.
The opportunity exists for all of us. Especially with video recorders in the palms of our hands 24/7, we might as well make good use of it by sharing special messages with our loved ones every so often. You could even put it on the blockchain if you wanted!
I haven't mentioned it for a long time but this is actually why I write some of the stuff I do. This is my legacy to her in some way, not just what I earn here, but my thoughts, ideas and how I try to live. Plus, what I think of her.
Now that you mention it, I do recall you having written this before! It's definitely a great idea. Maybe I should have thought about that before I started posting everything that I posted :-p
Looks like it's time to start a new account! ;-)
