This is just something I noticed because of my heightened understanding of body language now (thanks, Chase!). My professor asked me a question and I answered him. But when I was done, he kept looking at me and didn't say anything. I got slightly nervous and continued to talk. I realize that he had put the pressure on me to keep talking simply by communicating that he EXPECTED me to keep talking. Need to use this more with girls. And to not fall for this when people use this on me.
