The following is a partial list of references from which relationships were in-part modeled:
- “Common Sense.” Wikipedia. Wikimedia Foundation, n.d. Web. 21 Jul. 2004.
- Initially found vague references that were not useful
- After additional reference to dictionaries, found what made these references trivial was that they could not be put into action
- The remainder of the references have been deleted to preserve uniqueness of content
