Trigger: Garth comes home to his dog having dug a hole in his living room floor.
Problem: It wasn't just a one-time thing because he comes home the next day and the hole is even bigger.
Quest: How to get Kachina to stop digging holes in the floor? Garth tries many options, with mixed results.
Resolution: Garth gives up, and Kachina gives up on her digging.
Purpose: Hmm... this one is subjective. Perhaps, problems aren't solved in anger?
