Mine would have to be the first option. Allow me to explain.

See, this girl and I used to be really good friends, and then she decided to become really mean to me and be glad that she's mean to me. She's one of those types where if someone does anything that can be even slightly perceived as mean, she'll take it personally, but she can be as mean as she wants and thinks people should just deal with it. She had also been abused as a child -- her mother had anger issues and hit her a lot.

So I received some of her wrath last month for a reason that was none of her business. She totally went off on me online. So a couple days later the argument had resumed online, and once she realized she was losing the argument, she put up an away message.

I was still heated, and knowing that things weren't gonna get any better, and being really pissed and feeling the need to hurt her like she hurt me (if not worse), I told her, "I can now see why your mother treated you the way she did."

Let's just say she didn't like it much. That said, she deserved to hear it, for in a way I do see why her mother beat the shit out of her if she's like that. I don't hit chicks, but if anyone deserves it, it's her.
