A slightly disconcerting observation

The other night, the evening of the 4th, to be exact, some persons in the vicinity of my apartment window began merrily setting off (illegal) fireworks. When I heard the familiar whines and whistles of flying sparks, my very first thought was “gosh, I hope they don’t set the building on fire.”
Dear Lord, I have turned into my mother.
