(I know I'm a few days early, but I'm away at a retreat this weekend).

I find it hopeful that many realize that peace is important to the world around us to establish good relationships with others - regardless of another persons differences.
But at the same time, I still find it sad that it's localized to only one specific day. But it's a start!
How are you planning on participating? Is this the first time you've heard of this event/day?
Myself, I'm at a spiritual and social justice retreat this weekend, so I'd assume that they realize that Sunday is a very important day this weekend!
Peace, prayers & blessings for everyone.
