A) I think they have a wonderful life. There are many more conditions, school education is not as advanced as ours, the weather is very good and they have more beaches where to go. I think they eat fast-food or as found in many restaurant, refined and expensive food.
b) I think the most difficult thing was to get used to, especially in a foreign country and don't know much about. Language is quite heavy, with many diacritics and accents, difficult to pronounce, and that because they have a specific emphasis. Many Romanians don't make school at the right time or leave it, don't know how to speak English, so David and Alex can't really understand the Romans.
