So I have a few fairly new friends. Most are very quiet and shy except for one person who is super confident, friendly and LOUD... lets call her Lucy.
The other day the 6 of us had a barbecue where Lucy got a little tipsy while everyone else stayed sober. This lead to the conversation being completely railroaded about one specific book series that nobody else had any interest in. By the first 20 minutes or so, everyone had said something along the lines of "ooh, I don't really read anymore", so its clear that literally nobody else is invested in this book recommendation/plot explanation/analytical breakdown.
However, Lucy goes on and on about this series for 1-3 hours... I'm not sure it probably just felt like 3 hours, and I can tell everyone just wants it to end. I have actually read the book she was talking about and even I got lost in a lot of the description, so I can only imagine what it would be like for everyone else.
Because so many of us are ridiculously softly spoken, its down to me and one other guy to try and save the conversation. While Lucy continuing to talk about the book to this guy, he tried turning and just starting a new conversation, talking over her (but not as loudly). Lucy took offence, calling them out for being rude and ignoring her.
After this, I tried to jump on or make comments about the mini topics that were not directly book related. So although I slip in small comments or ask questions about other things. Lucy was so loud and perpetually in the middle of an important story anything I said would either get acknowledged and railroaded back to the book, used to further the book conversation or if it was too long or off topic, straight up ignored.
Its not usually this bad, in general we all love Lucy and appreciate how she keeps the conversation going and she definitely brings us all together. But it should never have even gotten close to the point it did.
So with priority 1 being to stay polite and on good terms with Lucy and priority 2 being save the conversation: how can I strong-arm Lucy away from a specific topic in the future, without her thinking I'm rude?
