Is there a quote that demonstrated that Beah lost trust toward people?

From the text:

I was quiet for a bit, as I didn’t know what to say and also didn’t trust anyone at this point in my life. I had learned to survive and take care of myself. I had done just that for most of my short life, with no one to trust, and frankly, I liked being alone, since it made surviving easier. People like the lieutenant, whom I had obeyed and trusted, had made me question trusting anyone, especially adults. I was very suspicious of people’s intentions. I had come to believe that people befriended only to exploit one another. So I ignored the nurse and began to stare out the window.
