Answer:
to motivate a friend
Step-by-step explanation:
The most likely purpose of this text is to entertain friends. The language that is used in the passage is not formal. This means that it is unlikely to be used to inform a college professor, to convince a school board, or to convince a potential employer. Moreover, the passage does not state any fact that would be relevant to any one of these audiences. Instead, it tells us of a personal experience that is likely to be interesting to the speaker's friends only.
