Looking at human relationship from an economic point of view

I read the post on our AP economics blog that compares friendship with consumer mindset and entrepreneurship. I found this interesting and started to think about how human nature, as we perceive it, would be used in economics and what the limit of it is, because I did find the concept of connecting the motive to form a friendship and the nature of economics, or I call it greed, odd at the beginning. Furthermore, the blogpost points out that a virtuous, true relationship goes beyond the scope of economics, meaning that forming such kind of friendship would be considered 'irrational'. Is the economics theory here right? Or is the assumption of human nature that the economic theories are based upon missing something?  And to link all these questions to myself, is rationality really 'better'? or 'fairer'. I am aware that I have been rambling a bit, and I do think I need to take some time to think this through.

Hsinchu Weather

Today's such a good day. It's sunny but not scorching, and there's wind that would keep my body dry when I'm out. I usually sweat a lot. I learned that it's raining like crazy in Neihu, where my home is, yet there were barely any clouds in the sky here in Hsinchu. This scene reminded me of California and made me really relaxed. I walked through the Hsingda campus to get to the gym, which is on the other side of the campus. There're trees along the away that blocked some sunlight and created some amazing silhouettes on the pavement. With some chirping sounds in the background, I felt that I was in a place where new age pianists would usually have their CD's cover photos taken to show some sort of serenity kind of feeling.
