"I need to go home ... now.." Rebecca said to herself, grabbing the can and putting on her jumper.
She walked out of her class but was confronted by the Headmaster.
"Oh, so you weren't slacking then, hmm? Good to see - I was going to fire your worthless ass if you hadn't have turned up. So far I have not seen any improvement in the quality of your students' work".
Rebecca's anger began to rise.
"And frankly Miss Clarkson you seem to be much more of a liability than before!" he shouted at her.
Rebecca decided she wasn't going to take that shit anymore. She lashed out and socked him round the face. Blood and two teeth spluttered out of his mouth as he spun on the spot and hit the ground ... hard.
Rebecca looked at what she had done. She hadn't known she was THAT strong.
