Way In the Past
It was a case of mistaken identity on her part, and she shoved into me in a nightclub then accused me of something as though I had been a friend of her and she had a knowledge of me, only very much later realising I was not her friend but had the same hairstyle and a simliar top. I ignored her, which she seemed to not like, she shoved me in the back into my friend and her drink, and I then turned round and punched her in the face.
In High School, I hit my former best friend but that is basically what you do in High School, and typically forget what it was about, but it was deserved.
I seem to have hit a lot more boys than girls whilst growing up.
