According to Dictionary.com, Archetype means:
1. the original pattern or model from which all things of the same kind are copied or on which they are based; a model or first form; prototype.
2. (in Jungian psychology) a collectively inherited unconscious idea, pattern of thought, image, etc., universally present in individual psyches.
We experienced an archetype earlier this morning in our house, one of those collectively inherited unconscious ideas, shortly after I made waffles for the boys. Devin, based on the archetypal notion that if your brother has it, it must be better than what you have, insisted that he wanted Trevor's waffle. Not realizing an archetypal idea was at play in our household, I switched the waffles. Of course, this accomplished nothing because of the aforementioned archetypal idea that his brother's waffle is better than the waffle in front of him.
Archetype or not, I tuned him out after the waffle switch failed, and ultimately someone (it may have been Socks) ate that dadgum waffle.
