Bit of an old thread but I thought I'd have a play with this. I've had fifty years practise at trying to get this sort of thing right but found that if I looked at the pictures first without looking at the answers I had no idea about nearly all of them. One looked like someone squinting into the sun. Most just looked neutral. A couple seemed to be flirting with me which turned out to be wildly inaccurate!
If, however I spent some time looking back and forth between the pictures and answers I did really well - 30/36.
