Describe the cultural change at the end of chapter 7

On the sixth day of his sojourn, Beah finds a group of eight people - four boys, two girls, and a man and woman - and approaches them carefully. He addresses the man in both the dialects of Krio and Mende, but receives no response. To his specific request for directions to Bonthe, an island rumored to be safe from the RUF, Beah receives a response from the man in Krio. The man gives him directions, but makes it clear from his face and posture that he wants Beah to move along. Beah continues on his journey.
