Youth in Denmark
The use of English is frequent among young people under 25. English is the predominant second language and is in the school curriculum from the first grade. Roughly 90% of 15- to 21-year-olds speak English with other Danes at least once per week. Youth code switch from Danish to English with friends and classmates. English phrases or words are spoken in between Danish words. Codeswitching is a marker of youth identity and sign of opposition to adult culture. Youth use their language style to differ from adults.
Sørensen
Sørensen is a Danish-Norwegian patronymic surname meaning "son of Søren" (given name equivalent of Severin). It is the eighth most common surname in Denmark, shared by about 2,3% of the population. 
Immigrants to English-speaking countries often changed the spelling to "Sorensen" or "Sorenson" in order to accommodate English orthographic rules. English-language media often similarly renders "Sørensen" it as either "Sorensen" or "Sorenson". A parallel form of similar origin is Severinsen.
