GagaJo, you say ‘It's just boring, listening to someone drone on about stuff’. Isn’t that at least partly true of any topic that doesn’t particularly interest the listener? It might be a political hobby-horse, or an obscure hobby, or an obsession with a celebrity. Talking about things that interest oneself to the exclusion of the interests of one’s interlocutor may be clumsy, or thoughtless, even lacking in manners, but it doesn’t make one a bad person. Ascribing unpleasant motives to someone simply because we don’t enjoy their topic of conversation is uncharitable and unkind.
How much do you spend on yourself?
