I've moved around a lot, and in between countries too. Making friends when you are older gets harder, and if there is a culture difference it gets even harder.

I've moved around a lot, and in between countries too. Making friends when you are older gets harder, and if there is a culture difference it gets even harder. That said, I've also gotten better at it over the years. You see this sort of thing in people who have spent big chunks of their life as an expat. There are also places around the world that have a lot of English speaking expats around, where it's fairly easy to make friends. These friendships aren't all long lasting, and you only manage to keep a fraction of the friends you have made in a new location. That said, you do value good friendships a lot more and will make the extra effort to travel to see these people.
