Please be gentle! Lurking for ages but first post.
Every time DM and I speak, the conversation is dominated by discussion of her friend to the exclusion of all else. I'm pleased DM has this close friendship but do feel like she never wants to hear about what we're up to.
I've never met the friend but she sounds nice enough. I think DM over-sells the friendship to knock me (so as not to dripfeed, she has form for this kind of thing) eg "xxx's kids call me gran now", "xxx gave up work as her kids are more important than her career", "xxx bakes all her own cakes and always offers me at least three options", "xxx is like the daughter I never had" (!) and so on.
AIBU to politely steer conversation back to common ground when she starts on like this?
