[Early in the day, there's a boy with shoulder-length, bright yellow hair sitting down near the large sakura tree in the park, gnawing at the top of his jar as he tries to open it, with no real result, of course.
After a moment or two of attempting this, he stands up, then looks around until he finds a rock, walking close to it, and tossing the jar hard at it.
The jar bounces off the rock, and smacks him hard on the face.]
