Why do some boys think im a boy and when i ask them why they say because you're tough

They all do things related to agriculture as a source of living. Some are fishermen, or farmers while some are just hunters. Some rear animals.

Explanation:

The Native American tribes are tribes that have been in America even before the Europeans came down to the United States of America. Native Americans are called " red Indians" because the Europeans discovered them through their search for the nearest way to India. The native Americans tribes are more than one tribe with different way of life or culture

Despite their different way of life they were all known to depend on Agriculture (the art and science of cultivating the land and rearing of animals) as their source of living for instance now the Hopi are known for farming while the Chinooks are fishermen.
