which describes how you're feeling all the time

Liam is working on learning how to express his emotions in words and expressions rather than, say, hitting or kicking anyone who gets in his path. At dinner one night, we were talking about what it feels like to be happy, sad, and angry, with accompanying facial expressions. This one was supposed to be "sad" -- see how his lip is sticking out -- but he kept breaking up laughing while showing us how sad he was.


Guess which one this is?
