My buddy warned me about the mint the pervious owners planted, and I pulled it right away. It was right by our basement entrance so I frequently peer in and inspect for mint shoots. I think there must be a buried barrier or something (like landscaping cloth) preventing it from spreading outside the bed it was in. I found a small sprig 4 years after pulling everything I could find.
Jesse Brown from Canadaland had long lamented Canada’s inability to define itself except in contrast to Americans. He’s right that we ought to have more positive identity markers but I think it has inadvertently resulted in a very robust independence sentiment. Ie because so much of our identity is defined as differences relative to America the idea of being American is offensive to the core of our identity.
