Thank you so much for your sympathy. My dad passed a couple years back and my mom passed a few months ago. I still wish to communicate with them even for the last time in any way.
My sincerest condolences. If it were me, I'd ask what advocacies and such of theirs they would like me to continue. When we are all back to the dust from which we came what is left is our deeds. If continued by our sons and daughters they will become our legacy.
