What are the explicit and implicit details in this passage? Passage↓

It's a lovely summer day, and Larry and Charity have an hour of free time before Charity's bobsled tryout. They decide to go to Spollen Park to play Frisbee. The park is huge and has very high walls and gates that are locked every night at sunset, though park rangers do patrol late at night. As they're playing, Larry accidentally throws the Frisbee high up in a tree. He slowly walks to the tree trunk, but when he looks up, he instantly gets dizzy and nervous. Charity shoves him aside and climbs the tree to get the Frisbee. Way up in the tree, though, Charity's foot gets stuck in a branch, and she can't get unstuck by herself. Way down below, Larry yells for Charity to hurry up, and just then he notices that the sun is starting to set. He looks up, and Charity is scowling down at him with her arms crossed.
