The wars of past and present

It's Remembrace Day, so we start your weekend reading with some articles from Canada and abroad about war, flowers, poetry and how conflict can bring justice. And for the rest of the weekend, learn about everything from crop circles to kindness.

It's a long weekend for some Canadians, but not for the crew at The Conversation Canada, so we'll be back in your Inbox on Monday.

Regards,
