We are taking a short break over the holidays and are rebroadcasting some memorable discussions. This episode was originally published February 9, 2021. The pandemic has shrunk people’s lives. We’ve been limited to seeing the people in our homes, some family and maybe close friends. What happens when lose contact with acquaintances and serendipitous interactions in the world?

Amanda Mull, staff writer for “The Atlantic,” wrote an article about this and joins “This Matters” to discuss.  If you would like to support the journalism of the Toronto Star, you can subscribe at thestar.com/subscribingmatters.
