Definitely and increasingly so as I’ve got older.
I enjoy being round people in the day, but I’ve found increasing solace in being on my own at night and (rarely) weekends. I truly love having a whole weekend to myself, although the demands on my time are such that it’s a fairly uncommon occurrence. I love the selfishness (and self-indulgence) of doing what you want, when you want, including going out for a drink on my own, although I always bump into people I know whenever I do, so it’s not quite the full monty, I suppose.
I can’t say I’ve ever felt lonely, except for the first few months when I moved to Birmingham six or so years ago, which elided with my marriage breaking down. Otherwise, I have tended to gravitate increasingly towards solitude since I turned 30.
I would also say it’s been a stumbling block to any subsequent relationships going the distance, as I just don’t want to spend as much time in my girlfriends’ company as they have wanted or expected from me.
It’s one of the reasons I reckon I spend so much time on here. It enables me to interact and communicate with others, whilst being in my own company and not having to make any effort in engaging with a conversation that I am disinterested in.
I think I’m basically a fairly benign, but selfish ****.
