Input: A little background. I worked with this woman for a few years. I did not like the woman for various reasons and it culminated in the signing of the card when she left.

At work, she would do the bare minimum that was required of her and generally just didn't care about the people she was meant to be there to help (we work with teenagers). When she went on maternity leave, she spent the last few months of her time at work slacking off and not having her students do the work they were meant to do, which we didn't find out about until after she'd left; she'd effectively downed tools because she knew it wasn't going to be her problem when she was gone. We ended up having to redo all of her work on top of our own. She would also be the only one referring to our transgender students by their "old" names and pronouns, even when they'd never been referred to as those names and pronouns and they were only on the system because they hadn't legally been able to change their name yet.

Then a while back she was renting out her apartment because she was moving in with her long-term partner, and I was looking for a place with my best friend at the time so we ended up renting the place from her (this was before quite a lot of the stuff in the first paragraph had happened, we'd only been working together for about a year at this point). Turns out she was a bit of a nightmare. She refused to do basic things such as put locks on the bedroom doors telling us that "if you're such good friends, you shouldn't need locks", and even when we offered to pay for them ourselves said she wouldn't allow us to have locks and it was "non-negotiable". It basically became a running theme that if we wanted it, we weren't getting it regardless of if we would pay or not.

She also wanted nothing to do with my friend who was paying half the rent. If my friend asked her a question on the groupchat, she would often answer in a separate chat or phone call to me specifically. When it came time after a year to renew our agreement, she send a list of amendments that straight up said "All communication regarding the apartment is to be between me and IFeelRomantic". After a while because of this and some other warning signs I figured out she was committing fraud, pretending to her mortgage company that I was the only person living there. I could have shopped her, but I didn't want to cause problems at work by essentially turning a co-worker into the authorities. We were planning on leaving as a result of all this, but she ended up selling the apartment anyway after we'd been there 18 months.

So essentially due to all this ... I wasn't her biggest fan.

She quit the job recently, and a leaving card was going round the office. I was trying to pretend I didn't see it or I was just too busy, but it eventually got dropped specifically on my desk and I couldn't. I didn't have it in me to write a love-dovey message after the crap she'd pulled. So I just wrote *"Bye bye! - IFeelRomantic"* in the card. I could have made up some fake BS, but I didn't.

As she's leaving the building for the last time we happen to cross paths as I'm coming in from break, and she has a go at me for writing the message in her card. She says "that's all I get for all these years working together, all the things I've done for you?" (referring to letting us rent her apartment presumably, since she damn well never did anything for me at work) and says she knows I hate her even though she doesn't know what she possibly could've done to deserve it. I just tried to get out of there as quickly as possible since I didn't want anything to do with her at this point and I was hoping to avoid all contact whatsoever.

AITA in this situation?
