Why did Angelou believe she could pass as any young Ghanaian woman in Dunkwa as long as she didnt talk too much?

Angelou believed she could pass as any young Ghanaian woman in Dunkwa as long as she didn't talk too much because she felt her physical appearance resembled that of the local women and she could blend in easily without drawing attention to herself. She recognized that her accent and manner of speaking were the main factors that could potentially give her away as a foreigner.
