Even though I had already experienced being new in a foreign country when I moved to Denmark, Poland was a completely new experience. Whereas Danish is similar to German, and I could at least read virtually everything without much practice, the Polish language is entirely different. I could get an impression of how my foreign colleagues must have felt when they moved to new countries to start their PhDs. But since the Polish people are open and helpful, I never felt unwelcome, despite the language barrier.
