<human>: This is a bit of a rant, but I have a recurring problem with an older family member I'm not sure how to deal with. Basically every conversation we have turns into a lecture. Things actually start out pretty normally, but after a short interval (about 10min) she will begin to talk in a slow, measured pace in unnecessary detail about issues she has described to me before, or events I was present at. It can become very infuriating, especially when I know what the point of the story is but she insists on finishing her meandering tales anyway (if I interrupt to point out I know where she is going she will just tell me to "let her finish", which can take up to 5 minutes of continuous listening on my part).
Any attempt by me to point out that I think the conversation is becoming a bit one-sided is met with hostility (shouting and aggressive remarks, to the point of hysterics at times). I always keep my cool in these situations but attempts to voice how I feel are always met with yet another aggressive lecture.
I love this family member deeply but I seriously need some ideas on how to reason with them. I'm fairly certain I am not the one being unreasonable in these situations but of course there is always that possibility!

Can you provide a brief overview of the text?
<bot>: Older family member won't stop lecturing me! I feel this is getting in the way of us having actual conversations.
