Question 4: Brought to you by the Letter Asshole

It has always amazed me how two-faced people can be, but not in the high school sense. I am talking about those who say one thing, but do another. Those who play one side to ellicit something from the other. Those who spout out empty words to make themselves look better only to fall on their faces because of their actions. I have been the victim of no less than three of these people in the last 2 weeks. Nothing horrendously bad, nothing I did not already expect from these people. At least I can say they did not disappoint my expectations of them being smarmy people who only become involved when they want or need something, then go AWOL until the next opportunity presents itself. And you know that saying something does nothing because it only ends in blank stares and endless illogical defenses that leave you frustrated and annoyed. So that being said:

What negative (in your opinion) aspect of people's personality has always amazed YOU? Something that you could not fathom doing or being yourself because it just seems so wrong.
