I really wasn't trying to be funny. When I want to shoot "culture", I've found long lenses the best. They give you a stand-off distance, which in one aspect, is very non-threatening to the subject. And, most times, they won't even notice you. About the only thing that is lost with the usage of telephoto lenses is a narrow DOF.
Of course, I never, never take pictures of children unless I get permission first. It's easy with my grandkids because I can shoot them all I want, and if there are playmates around interacting with my grandchildren, them too.
