calm down?

yesterday at lunch i was sitting outside enjoying the beautiful sunshine. (and maybe wishing i had been wearing sunblock...) i heard a man in the parking lot start to get irritated by honking his horn at the driver in front of him (who wasn't moving, i'll give him that). he started honking more and more and yelling (his window was down). then all of a sudden he started breaking out into song "HOW GREAT IS OUR GOD!! SING WITH ME HOW GREAT IS OUR GOD" at the top of his lungs. it was quite amusing and also a bit disturbing to see such anger and then hear him singing a worship song. wow.
