JavaOne - Social Aspects

So, I'm actually one of those people who turns to the people next to me at sessions and introduces myself and asks them what they are doing, etc. Maybe we chit chat about where they are or how the session applies to them. Okayyyy, I admit that I did this at the beginning, and then towards the end I was just anti-socially playing my PSP.

Anyways, I would say approximately 60% of the responses are good ones. I.e. people will respond and you will have a mini conversation. But, those aren't the interesting ones. The interesting ones are when people start shaking and stuttering when you start talking to them, and you can't help but feel bad. Are people so lacking in human interaction that they can't talk?

And, there was this other person I introduced to, and the conversation went like:
Me: Hi, my name is Brandy.
Other: My name is blah.
...We shake hands...
Me: Where do you work?
Other: At Blah in Blah.
.... and yeah... end of conversation.
About 20 minutes later, I see him pick his nose... I broke out my anti-bacterial hand wipes fast.
