In the story borders why did the speakers mother want to travel

In the story "Borders" by Thomas King, the speaker's mother wants to travel because she identifies herself as a member of the Blackfoot tribe and wants to exercise her rights as a sovereign nation. She believes in the importance of her cultural identity and refuses to carry a Canadian passport as it goes against her principles. She wants to challenge the concept of national borders and assert her own people's sovereignty. By refusing to acknowledge the imposed boundaries between nations, she strives to keep her cultural heritage and identity alive.
