Another thing for some Polish people is personal space(i have read that others think this also), this only happened to me twice, once in Poland and once in Ireland. In Poland a young woman working in a restaurant wanted to ask me a question and she came right up very close to me, she was so close I could hardly focus on her face, she was nice and I was amused afterwards. The 2nd time was in Ireland and a Polish guy who was talking to me came right up close to me again, when he was talking some spit was flying! Not so nice. I have been talking to him since and he seems to have adjusted to the giving people more personal space.
It happened to you twice? So hear me out, I have also experienced (twice) Irish people talking to me way to close. About saying hello; when back in Poland in a small town, also happened to me to say hello to a stranger (more than twice). Bth, there are a couple of other countries I know of, when you can hear hello from a stranger.
In my opinion Ireland should consider itself relatively lucky, I would say Polish in Ireland behave quite calmly (I know what they are capable of!). I think most meat-heads choose England instead of Ireland because there is more action, if you following me. I did choose Ireland for the opposite reasons and must say, although its a great country, its a bit boring to me.
Irish are quite passive (British legacy?). I know some (more, and more) Irish have 'issues' with immigrants and stuff, but they never tell you that in the face (they prefer the Internet for eg, or the radio to let the steam off). And you know what ... I lost my point so leave it as it is.bye
