Love the way someone else's point of view can teach you to see.
I especially like the St. Paul Cathedral one; I've been in there many times, and invariably, my head swivels on my neck just like Ed's camera seems to! But seriously, what if, just for today, everyone tried to see the world through one other person's lens? Especially if we chose someone with whom we don't get along. With a nod, of course, to Master Yoda: "Luke, you're going to find that many of the truths we cling to depend greatly upon our own point of view."
May the force be with you.
