Photo of the day: Cowardice
White feathers were once used as a sign of cowardice. Men who were deserters or even conscious objectors would receive them, usually anonymously (because the senders were too cowardly?) as a sign that others thought him a shirker. There have even been movies with that title, two of them I believe, where, of course, the recipients went on to brave deeds of derring-do that proved the senders wrong. The hero even saves the life on one of his detractors.
But there's no symbol here. Just two white feathers I found on a walk.
