I know Cork and the west best, having made many visits over the years. I love Ireland too, most people are fun and reasonably tolerant, but like anywhere it has its moments and being so rural and religious there are some remarkably conservative people there too. In the cities it helps the population tends to be young and there's music everywhere which always seems to help make folk more empathic.
Ireland is the only place in the world where it takes longer to pour a pint of beer than it does to prepare a meal. It positively encourages eccentricity which is possibly why it's relatively trans friendly? For instance, you can still find roads where the distances are in miles and the speed limits are in km, and I know of at least one village where the name is spelled different ways on the signs at either end. There's endless fun to be had.
But, it's also the place where we had a picnic on an island in the middle of one of the lakes and found an angler who was clearly trying to avoid us. In the end we asked him over and found him curiously reluctant to say what he did. In a flash, my friend intuited what the problem was and said, 'Don't worry, if you're PSNI, we'll bring you no harm.' The angler looked like a weight had been lifted from his shoulders and we had lunch together.
Afterward my friend, who'd lived in Eire for many years, said, 'I was born in the North and he'll have placed me the instant I opened my mouth. There'll have been times in that man's life when his next heartbeat will have depended on getting it right. Welcome to our splintered land and it's inability to leave its past where it belongs.'
By and large it's possible to steer clear of the more conservative folk though and in rural communities they usually announce themselves. With so many young Irish people having worked in the UK there's a bond we broke by leaving the EU but the place has a lot to recommend it.
One last thing. If it's raining, it's a 'soft day'. If it's bucketing down, it's a 'grand soft day', and if there's a monsoon, it's 'a grand soft day, thank god'. They don't call it the Emerald Isle for nothing!
