What is the topic sentence of the paragraph below, which comes from a communications textbook?
Our messages are given meaning by our relationships. A kiss, for example, has a different meaning when bestowed on your mother than it does when shared with your lover. In one relationship, saying "Let's be friends" (e.g., when said to a new acquaintance) is an invitation to explore relational possibilities. The same phrase, when said to someone whom you've been dating for the last year, can haven entirely different meaning (as in "Let's just be friends," which some say is the coldest sentence in the English language!).
