Swedish shyness

Why swedish people don't answer to our question?? I guess it's because 5 boys coming to ask, photograph and record you is too much for them... only 2 people of 8 answered to our question: "Could you tell us a public place in Malmö that has been special for you or you like for any reason?". Now we got divided into two groups so we can work faster and don't make the people get afraid...the 2 swedish boys will ask while the rest of us takes pictures of all around Malmö. We'll see if it works...and the people turns helpful.
