Agreed. My sharing is strictly academic since, sitting in the Wizengamot chambers with the Dementors circling overhead, someone kept her cat Patronus feeding them whilst she sentenced Muggleborns. It was dead cold, though. And I'm quite sure I would have been even more panicked had I not had scribing to focus on.
You know, perhaps it's the one and only way that some of those Death Eaters managed to escape Azkaban without being slobbering messes. I wonder if they focused on their little obsessions.
