John was restless in his skin, waves of prickly tension breaking over his upper back, settling in his neck, his shoulders, along his upper arms. He was leaning, forehead resting on cool glass, against a shop window displaying knives and various sonic devices. The shop was shut. His hands flexed against the glass, either side of his head, the tension apparent for anyone close enough to care to see.
A hand formed slowly into a fist, and he thumped the toughened glass, setting off a shrieking alarm inside the shop. John pushed off the glass, and pressed a few buttons on his wriststrap, silencing the racket. "You can just shut the fuck up. Whiny, fucking,
bastard thing."
Whether he was talking about the alarm or himself was anyone's guess.
He suddenly whirled on his feet as he heard someone behind him, hands already gone back to fists, punchy and ready to fight.
