Btw, I left Poland when I was still a kid, so when I last visited as an adult I felt much as a foreigner there. I have become quite Americanized, and since I never lived there as an adult, I have trouble understanding some of the cultural nuances of Polish culture, even though I am fluent in the Polish language, but for example I do not fully understand the use of the formal and informal form of "you" or rather how one would go about switching from one to the other without offending, and in general I am much more likely to accidentally offend people or not understand what is implied (said between the lines) in Poland because my culture is very different. I know some of the cultural norms in theory, such as respect because of age or because of position as opposed to the more common American respect must be earned, but even though I know about Polish culture, it is foreign to me now, and that causes friction between my parents and me for example because their expectations remain Polish no matter how long they have lived abroad, whereas I do not get Polish expectations at times.
