Characteristics of the Person:- Dogmatic and doesn't have a full stop in his conversation. He talks what he wants to talk, and isn't interested in what others want to talk or anything outside the scope of his interest. He just comes in says hello and tries to repel the conversation to what he wants to talk, and then there is no way to turn him out of it. But this isn't the problem.
Example of our conversation:-
Let's say he likes some
x product. He would talk about why product
x is a good one and everything good about it (and some made up stuff too), which is plausible. But the things is that in order to prove the superiority of
x he brings other related product
y and starts debating on why
y is inferior as compared to
x. This is quite detrimental, not only to others opinion but also ends up making him believe in some false information. I tried many times to rectify him, but due to his dogmatic nature I end up on the receiving end of irrational criticism. Due to this the conversation ends up having information having influence of his prejudice, rather then mere facts. As I mentioned he doesn't know when to stop. His conversation can go on for hours if nothing is there to interrupt it (Today we conversed for 4 hours about some stuff that is beyond our control).
The Actual Problem:- I am least interested in the conversation, because the same conversation happens everytime he talks to me, about some products that he likes. I am tired of listening to the same stupid stuff everytime, about why
x is greatest and other's are not. I tried several time to change the topic of our conversation to something else (more productive) but he ends up coming back to what he wants to talk regardless of other's interest.
Problem from my part:- My problem is that I just don't know how to express my lack of interest in his conversation. I tried to give him many signs depicting that "I am not interested in this talk" but he ignores them all and ends up talking about what he wants. And I am not a blunt person, who can go to a person and say "Get off my face" (which i believe would end up Hurting him). Due to this I end up nodding to whatever he says, without any interest for hours (Today, I wasted 4 hours of my life listening to this crap).
What Do I want:- I want some methods that I could use to make him stop bothering me. Or to make him realize that "I am not interested".
P.S.:- For those people who would answer/comment on me trying to acknowledge him about his behaviour, should probably stop coz I have tried quite a lot doing so but due to his arrogance nothing goes past his ego. So I believe work should be done on our side, rather then on his.
