Yes, indeed!
I can't say I have any friends at all really. Lots of "acquaintances" such as neighbours, people I know through a couple of hobbies and voluntary work, ex-work colleagues, even ex-school friends, who I'd stop and pass the time of day with for five minutes, if I met them on the street. But certainly no one at all that I'd go out socialising with, or to hobby/events with, or to phone/text/email for chit-chat.
I can't say it bothers me. What you've never had, you don't miss. For the past 36 years, it's been basically me and OH (he is the same as me). We also have very small family, none local, just us and our son really.
From what we've heard from talking to acquaintances and family, they seem to have nothing but drama with close friends, so many seem to be "needy", a few "friendships" have ended up with broken relationships with the "friend" having affairs with the husbands, etc. They all seem so over-invested in eachother's lives.
Both OH and I seem to prefer our "boundaries" when it comes to other people. We both also put up barriers, as we hate it when different aspects of our lives overlap, i.e. we don't like it at all when, say, an ex work colleague "crosses the boundary" and joins one of our hobby or voluntary activities - we prefer to compartmentalise our lives and our acquaintances.
That makes it sound like we hate people, but we really don't! We like a chit chat, but that's as far as it goes.
