Answer: More context surrounding the question would help me to better solve the question.
Step-by-step explanation:
I am guessing the following line is an excerpt from some class-sanctioned reading material.

Bees are small and lovely insects that often fly fast - by comparing their flight patterns to whatever your main character might be going through gives off the impression that they are in a stressful situation.
