As our generations are "owners of possessions" ... start NOW cleaning out your attics, garages, closets and basements. Pass on the 'treasures' of your families ... that great-grandma's carpet rocker, the crystal candy dish, that roll top desk, etc.
I have a house FULL of the history of my siblings ... I threaten and stuff their cars with "the valuables" each and every time they appear.
I was on the phone with a sibling about a niece's wedding this month ... suggesting we pass on wedding gifts from their deceased grandparents' who were retired before they were born. Beautiful items ... unique ... which I uncovered and now display in a small glass door cabinet in my living room. I "inherited" the family home; this niece might have 10 days over 27+ years visiting this family home .... and when my generation moves into nursing homes .... these treasures and their connection to their family, will most likely vanish.
