My best friend has had problems at work for some time now, but I'm starting to feel like it dominates 100% of the conversation when we're together. And most of the time, I don't understand what she means because I don't know the team understand much about her field - for example she will say "Linda, who is only on a point 13 salary, wrote the lone working policy and didn't even involve the HR director, I'm absolutely furious". I do ask her to give context but it just prolongs the talking about work and seems to confuse things even more.
This may sound selfish, because whilst I sympathise (I've been there before with working in a shit environment!) I am finding it so boring that I'm avoiding being around her at all. I also can't really give advice when I don't work in that environment or understand the full picture. I would quite like to talk about other things to do with me - for example I'm having major surgery soon, feeling really nervous about it and want to talk to her about it but she just steers the conversation back to her work: "Oh yes that reminds me when John had surgery and Steve didn't send him so much as a get well text. I hate Steve, etc etc...."
AIBU to think that this isn't a very fair friendship
