I grew up in Dublin. When I first went to America and saw people there who were of Irish descent, I could see that they had Irish features, but the big difference was that they had grown up with happy faces. Irish people grow up with a frown. I think this is because the weather is so miserable that they have to use their eyebrows as umbrellas.
funny thought)) I can't say anything because I did not live in Ireland and only visited as a tourist, so I've met only happy and smiling people in my way) I even thought about why they are so happy? how can you smile when such a terrible weather? but I believe that bad weather or country didn't have any meaning, if person is in a good company with good people and has a clear heart he will always smile)
