I was hungry so I painted the garage

The title "I was hungry, so I painted the garage" was an example of a non-sequitur that can be resolved with an intermediary narrative. For example, 

I was hungry and walking into town. I saw a woman working in the yard of a house and she said she would give me a meal if I painted the garage. I was hungry, so I painted the garage.

The point of this story is that the phrase "I was happy, so I patted the dog" works without an invented narrative, because we all know that passion evokes action. 

To explain "I was hungry so I went to the kitchen" is a little more work.
