I believe this one is pretty self-explanatory. You know the scene:
Child 1 has pet ladybug in self-made container mimicking bug's home environment. Talks to bug, plays with it, then notices it's not moving. Slight panic ensues. Child 2 excitedly exclaims, "I'll help you!" and runs to find an object with which to prod bug. Mother silently observes entire plight but gives that one objection. As child 2 disappointedly says, "Aw man," child 1 happily cries out,"She's moving! She's alive!" A celebration ensues and relief fills the air.
