I wasn't surprised by the information presented in this chapter. I've often observed social behavior in public - people in grocery stores stand in front of you, for instance or engage in conversation. Ever get stopped on a highway because of an accident? I have - in Florida - we all got out of our cars and communicated with one another about what could be happening. Social behavior might even explain the cell phone obsession as well - the constant need to stay in touch with those in our "tribe."

The bullet point that was especially poignant to me was #70, Laughter Bonds People Together. A few days prior to reading this chapter, I had just attended "Jump Start" with a group of web students from AIS. A small group of us met before and after the event and shared stories and laughter over food and drinks. Driving home afterwards - it's an hour drive for me - I reflected on our time together, thinking of the stories we shared and feeling happy about the evening and noticed that I was genuinely smiling. You can't fake a genuine smile, you really can't. People know, they see it in your eyes, your forehead, your cheek muscles, even your whole body posture. It's more obvious in person as well as videos, but lesser so in photos. In a psychology class at AIS we took a test, on BBC Science & Nature, and tried to guess if the person was really smiling - we got a few wrong!

Duchenne smile: Guillaume Duchenne was a French doctor who experimented with electrical currents to see which muscles controlled a genuine smile. He discovered that there were two major muscle groups: the zygomatic which raises the corners of the mouth; and, the orbicularis oculi muscle which raises the cheeks and makes the eyes crinkle. "Smiles that contract both of these muscles groups are called Duchenne smiles" - from #71, 100 Things Every Designer Needs to Know About People.
