I don't have any friends, so any IRL conversations I have are with family. I'm kind of shit at it though, 20% of my "conversations" are me prattling on about something autistic that only I care about, and the other 80% are me being completely silent or giving one word answers.
I'm very inexperienced with online communication too, I stopped doing it about 7 years ago, and I've only started doing it again within the last few months, this time with various strangers from 8chan rather than people I knew in school. I've noticed about 95% of what I write begins with "I" and is entirely about myself, and I'm not sure how to fix that or if it even requires fixing.
I feel like I'm okay if I'm being asked specific questions, but as soon as things start getting vague, small-talky, or about someone else's life, I just don't know how to respond.
