Identify who the conflict is between in this passage:
Rick raced down the bike path. Ominous dark clouds gathered in the distance. It was crucial that he get home quickly before it started to rain. Suddenly, his bike hit a rock and he flew forward over the handlebars. Stumbling to his feet and bleeding from his forehead, Rick shouted angrily, "Why do I always have problems on this stupid trail?!? Now it's going to take me even longer to get home. I'm going to get soaked for sure!" He hopped back on his bike and rode off, slightly swerving, trying to beat the storm.
What is Rick and the storm?
