I have moved "recently" to Ireland and I find it difficult to make friends here whatsoever. I believe that making friends in one's 30s can be a bit challenging even in one's own country. But I guess in Ireland the difficulty is doubled, if not tripled.
"Recently" means around 10 months by now.
If anybody is willing to meet for a coffee or tea, I would be more than happy to do so.
One of the main reason is probably due to cultural differences – that's why people have diffrent relationship patterns and expectations. I come from a more collective culture in which people think about others, people can rely on each other, are honest with each other, authentic and relationships are deeper and only then can it be called friendship. Someone here says that he has a friend, and the only thing he has in common with him is that they will go out for a beer from time to time to have small talk.
