What do you like to talk about?

I keep feeling alone in such a fundamental and inconsolable way. I feel like I have nothing to say to other people and other people have nothing to say to me. I talk to so many people all the time, but after asking about their occupation, their interests, their hobbies and how they got into them, what kinda music/books/movies they like, current events, different ideologies, talking about whatever context we met in, I feel like there's nothing more to talk about after that. Besides, knowing these things don't really make you feel closer to someone, do they? It's so desperate and frightening to never be able to quite reach other people... I try very hard but it doesn't work. There's no warmth between us. Maybe they can tell that I'm and actor and that I feign my interest

So what do you like talking about? What are questions that you like asking others? How do you harbor interest in other people or friendship?
