UK, Ireland / Are the Polish in the UK actually rude or bitter? [38]

So I have this friend at school, she's Polish ofc, and sometimes I get the feel like she's a bit rude at times. I would ask her something or call for her and she would give me a cold "what ?" And in general she's pretty bitter in how she acts and is often what people would call "brutally honest" She does however treat me very well on most occasions, so I started wondering if maybe that's just the way she speaks, I'm learning Polish rn and I noticed (like other Slavic languages) that its a very "direct" language, so maybe its got something to do with it
