Severus strode none too calmly up the steps leading toward the dungeons, his usually curtained hair almost sticking out in wild cow-licks, his lips unnaturally red, his tie loosened and hanging in a scruffy mess around his neck.
Banging through the outside doors leading towards the lake, Severus breathed in calming breaths before dumping his bag and books underneath the oak tree with a loud 'thwack!', sending some birds off in flight a couple of trees away.
Bloody first years... wouldn't know the difference between a sleeping draught and a shrinking potion if it bit them in the arse!!
Pacing back and forth to calm himself, Severus rid himself of his outer-robe, so he was just wearing his shirt and school trousers. Reaching into his back pocket, he retrieved a cigarette and put it between his lips, before lighting it with his wand.
