Afer my reflections on attachment, I was moved to discover this musem: The Museum of Broken Relationships. This is what the website has to say about the project:
Museum of Broken Relationships is a physical and virtual public space created with the sole purpose of treasuring and sharing your heartbreak stories and symbolic possessions. It is a museum about you, about us, about the ways we love and lose.
The Museum has two permanent physical locations--one in Zagreb, and one in Los Angeles--and has displays of some of the contributions online as well, stories and symbolic objects alike. It hosts exhibitions internationally as well, for a day, a week, a few months...
Take a look.
