I have an inordinate interest in espionage and subterfuge (for a SAHM). Just found this fascinating site about facial microexpressions and a test to see how good you are at detecting microexpressions. I think I scored about 6, but I had to view some of them several times. I am thinking about buying this training programme so I can get better at reading my kids. They will only believe in my superpowers for another couple of years, then I'm going to have to get my game on. This blog, Eyes for Lies, about lie detection might help!
