A group of people are walking down a rural street.
Some people are window shopping in a street with big buildings.
Just because people are walking down a street it does not mean that they are window shopping. People can walk down a street but not be shopping. Not all streets have big buildings. Rural streets especially do not often have big buildings on them.
