I am wearing a safety pin everywhere I go.
I keep a dish of them by the front door.
You can follow this link for the origins and how wearing a safety pin has become a symbol of peace in troubled times (or read on for my simplistic version):
The wearing of a safety pin signifies that you are a safe person and will stand with and welcome anyone no matter what they look like, who they love, where the originate, or how they worship. It has the potential to secretly encourage the discouraged or be a beacon of friendship to one who is in a threatening situation. It can also serve as a constant reminder to the wearer that love and kindness truly matters.
