When you talk to people just ask them questions about themselves (without being interrogatory!) as so many people love the chance to talk about themselves and it shows you're interested and a conversation could develop from whatever they say. Also.. you can apply philosophical thinking to so many areas of life. I bet you could get some good conversations going with what you know.
I can definitely get some interesting conversations, the problem I often encounter though is that the people I was surrounded with (I am currently not in education because of other problems, but when I was), would rather talk about sport, games, girls, etc. since I am 19, and my peers are around the same age.
That is why I have often found that people that are older then me are easier to talk with, since a lot more of them are able to talk about the complexities of life, and fun philosophical ideas.
Which is why I still hold hope for it being better when I get into some form of employment.
i used to have interests but they are really limited but i ain't always gonna know long they will last before i feel numb again and can't feel emotions
Can definitely relate, though philosophy has always been stable in that I have never lost interest. (except when depression hits, then everything can feel just as enjoyable as watching paint dry).
I also used to like playing video games, but that is sadly gone now.
