This article about Boomers downsizing and their children not wanting their stuff made me smile, as I have had this experience when I downsized, and I now actually live in a city with my memories on a blog, just like a Millenial! There's a big box of hard copy photos waiting for me to organize into scrapbooks when I get back home to America though. I guess this article is telling me: don't bother.
Maybe the reason Millenials aren't defining themselves by possessions is they all saw this movie short "The Story of Stuff" growing up:
Thanks to my friend Hope Gross Mandel for the article.
