Most Interesting concepts

The concepts I have found to be the most interesting had to do with relationships.  Particularly, how a relationship is built between between and how factors come into place when a relationship dissolves. I had (not MANY), but a few experiences of my own to read that section of the book and think back on why a relationship didn't work with a person.  I didn't actually think that relationships could be broken down into models, and we would place restrictions or barriers or even "standards" on others for why or why not we would date one another.  I found this concept very helpful in my real life, not just my school work.  Thus, the building of relationships all based around communication was helpful.  I even got quite a kick out of hearing how a partner does "secret tests" on another partner in order to challenge his or her commitment.  I didn't realize that I do secret tests on my boyfriend, and visa verse, it just happened.  Even though relationships are all different, I do believe these "guidelines" or models of answers can be somewhat tied into every relationship just somehow.
