Greed - short story

Johnathan entered through the window. The bank’s office was brightly-lit and extremely well-insulated. It made an appeasing change from the bitter cold of the night. Outside, the fog was omnipresent and the civilisation undetectable. Johnathan or John, as we like to call him, stared out of the window that had been currently left ajar. The gloominess left him unfazed. In fact, the absence of people made him feel serene. He was, and he loved to admit this, a self-diagnosed misanthropist.
He started towards the door of the office. Exhaling a sigh of relief, he knew he would encounter no outrageous mortals on the other side.
Kat entered by picking the lock of the staff entrance. She expertly utilised her hair clip to overthrow the useless security system. She straightened up, replaced the clip in the underside of her hair and haughtily ambled into the bank.
