I Just Heard An Explosion

Well, that was unsettling. It’s 2:15 AM, and I just heard a loud, echoey explosion outside my window. It sounded like it was about a mile away. It was very disconcerting. Plus, I was playing a game of Scramble on Facebook when it happened. Needless to say, I became very distracted. My score was undoubtedly affected.
