To not understand this?

[Insanity012]

Colleague left work the other week. Mainly because of the behaviour of other staff members towards her.
However, on the last day she showered them with praise and hugs, said she hopes she will see them again and still has them on FB making nice comments on their posts. She has been complaining about them for months to me and even nearly been in tears at one point.
Aibu to say this is odd behaviour ?

Are the people who were unkind to her also unkind to you? Do you feel she's let you down in some way by not using the safety of her escape to show them what she thinks of them?

No I agree op. Fakery from grown adults is insufferable. I wouldn’t be keeping in touch with her. Like you say, untrustworthy.

I'd be wary of putting this down to fakeness. It sounds like there's insecurity there and she just feels the need for acceptance, even if it's from people that have ground her down. It could be an emotional safety barrier and I'd be hesitant to judge her for that. Find it fake all you want but you can never really know what's going on in people's lives, or their past experiences, especially if there's been bullying or emotional abuse.

Or you could just ask her why she's doing this, then make your judgements after.

The colleagues were never unkind to me, no.
I don't agree with how they treated her but she as I came to see was not entirely innocent either.
I don't think I will hear from her again now. What's ridiculous is that she will have contact with those she allegedly can't stand but with me who was closest to her in work, there will be no more contact.
Either way, I may be left surprised but I certainly won't be chasing her.
Lesson learnt on my side.

I don't know if this is quite the same but there are many people who haven't been nice to me at times. But most people have nice sides even if they r horrible to you. I am that person who will be nice to someone however horrid they r to me or others. Because that's just how I am. Maybe your friend is like this too. Maybe she hates the way these people treated her, and maybe they drove her out, but she can't help but see their nice side and want to b nice to them.

Perhaps so. But then fake to say to me how awful they are and what terrible workers they are. That isn't just being the better person or seeing the good in someone despite what they are showing. It's just fake.
