I know. This is what happened:

I (30, F) had a friend (31, F) in high school, not close, but we used to hang out with this small group and have a lot of fun together.

This friend had a girlfriend, Sara (34, F), who lived in another town, but still nearby, and their relationship was absolutely crazy.

Both cheated non-stop, fisically hurt each other by throwing things, pushing and grabing and the had massive fights in public that once ended up with people calling the police.

That said, I only saw this girl, Sara, in person twice and was drunk both times. I knew all the drama by my friend and the group.

Fast foward a little and we have a sleepover on my friend's house where she had sex with other girl. Nothing new, didn't bet an eye.

Than Sara started to, in my understanding, force a friendship between us. She would invite me to every party, every gathering, until she said she would be here where I live for 2 days and maybe she could come by my house.

I'm not a bit timid, but I am reserved. I don't take likely spending my time on people and I barely knew her, so by luck nothing happened and she took the hint.

Soon after that the girl my friend had sex with came to me and told me they had said Sara my friend cheated on her with me, instead of this girl.

I didn't question nor berate them for it. There was no reason that would make that behavior acceptable and in people this out of touch words are but a waste of breath. I didn't hold grudges either, I just passed them from "superficial friends" to "people I know enough to say hi, but that's it".

Fast foward a lot, back to present. I was waiting the ferry boat when this other woman walk to me. I had no ideia who she was, wich did not please her and when she tells me she's Sara I still don't make the conection. I've known 3 Saras beside her, saw her two fucking times years ago.

She then started talking really loud, almost screaming and that's precisely what made me promptly remmember her.

She was still mad about "me" sleeping with her then girlfriend back in school. She goes on about it and I start to get aggravated by the proximity and loud tone. Asked her to back off me.

She mocked that I was avoiding her back then for fear and what, was I scared now too?

I was pretty much scared shitless, because someone who acts like this for something that happened 12 years ago in school is a whole new level of crazy. I say this as someone who's level 2 on the spectre. I'm used to be found unnerving, but there I was, thinking if I should just start running and to hell with the ferry.

Then she went for my arm and I hit her. Simple as that. I slaped her face when she tried to grab me and people who were already looking came to break the "fight". I had never hurt someone on purpose before and don't know what to think.
