Believe me,they are rude. I was so surprised,when I came to Ireland at the very first time which was 5 years ago,when someone steps on you by an accident,the person says "sorry" and stuff,you're saying the same.But if something similar happens in Latvia,,you'll get stepped twice and that person will swear at you or will push you back.It's not nice at all.And I believe that at the airport or anywhere else everyone will look at me,I don't know why Latvian people do like that,it's just dumb. And according to Irish people,they're warm and welcoming.
