Hey everybody!, I wonder what does Polish ppl do for christmas because, i was asked for my boyfriend to spend chritsmas with his parents as his parents are coming from Poland to México to spend christmas here, but i have no idea how they will spend chirstmas time here, because they will be in my country but somehow i will be the only mexican in the dinner so... any advices, what do u usually do for christmas?. By the way i haven't met the family yet and i don't speak polish so that makes me a LITTLE nervious :S
