Patty and I went for a brief walk tonight, just to keep our streak alive (we're at 4.) While we were walking, Patty mentioned that it was chilly, and then did two quick blows of the air to see if her breath would show. I didn't immediately clue into what she was trying to convey, so I immediately felt anxious, squeezed Patty's hand and demanded of her, "What's wrong, what's wrong?" I realized that even when we are engaging in relaxing activities, it takes very little to be jerked into this heightened state of worry. It's a bit embarrassing, really, whenever it happens.
