When I am able to speak about subjects that presently interest me (presently Norfolk coastal bus routes and rides (not inner city ones), sharks and playing piano) or past interests (of which I have had many) but otherwise no. I can ask questions about the person but tend to struggle to keep it up. Brain wants to wander off and do it's own thing unfortunately and I am not an overly social person anyway. I kind of resent society for trying to force me to be social when I don't feel like it.
I don't mind being social when I am in that kind of mode, but my passions are more precious to me than hours of company and social chit chat (unless they want to join me on a bus ride) and I tend to need my alone time to recharge anyway.
Only a few people over the course of my nearly 40 years on earth have let me ramble on about my passions, unfortunately.
It has always confounded me, but with a few exceptions, although I desire bonds in my life and a life partner, I do not usually wish to be social. It is strange. In short I want friends/bonds but don't want to have to socialise most of the time!
