Sergei considers the goldfish to be his friend. From the statement, it
is shown that Sergei has trust issues with other beings (May it be a human or
animal). He may have a dreadful experience in the past that prevents him from
befriending others. And he made an exception with the goldfish because he found
out that the goldfish will not leave him even if he is troubled.
I think the statement is true. <span>Words give people the tools to understand the world by creating and using their experiences. Words are a powerful tool used by people to communicate and connect to the word. Hope this answers the question. Have a nice day.</span>
