Yes.
Which is how I've ended up having HE friends mainly online. And they are scattered all over the globe rather than being on my doorstep.
It feels a lot like how my long term, "expat" friendships have developed.
Initially it was lovely to find a group of RL people with whom I had in common the aspect that made me "odd" in general. To learn the ropes and let off steam when needed. But ultimately the pool was so small that a common language\nationality\educational choice wasn't enough to compensate for all the things that we didn't have in common. And I found all the niggles of being an expat\HEor, rather than being soothed by like minded company, ended up being magnified and exacerbated cos we managed to work ourselves up into a right negative state by focusing too much on the things that made us blue. I felt I was "ghettoizing" myself, isolating myself into being "different" fulltime and that felt worse than pushing through initial roadblocks with the pool of potential mates in the wider RL community.
I've got a smaller group of RL friends compared to before I stated HEing, cos some just couldn't get past it and the constant nitpicking was annoying. Plus if you are going to stick me in a box, or keep poking me based on one perfectly reasonable thing I do, then you weren't that much of a mate to begin with. But those I've been left with are far stronger friendships than they were before, thanks to the additional connecting that comes with accepting and liking people for who they are, even when they walk slightly out of step with you in some way. We has some wobbles, but I'm back to being just Sarah, rather than "That Sarah, the one that won't send her boy to school !!!!!!"
It took time and I did have a few jittery lonely months out there, two steps forward, one step back sort of thing.
I need my HE clan and love my HE clan, but having HE in common isn't enough on its own to make things work for me, there has to be more than that to give us a basis for real companionship. So I found being selective with HE\expat AND "label free" chums, while limiting the numbers, gave me the chance to develop a higher quality of friendship.
HE doesn't make me fundamentaly less ordinary\normalish, anymore than being English does. I like being bog standardish. It is far more relaxing and comfortable to sink happily into the armchair of my "highly unexciting" status than march around sticking labels on my head that jump up and down about me supposedly being "very different"
I just can't keep up the effort required to go around pretending I'm "special" ( =
Thankfully I've managed to find the right people from both my "special interest" groups and the rest of the world that are fine with hanging around me, despite the lack of bells ans whistles attached to my person.
