You had started to believe that there was something wrong with Caine. He seemed a lot less social recently. He seemed to just be isolating himself from everyone. And when anyone did talk to him he was always so quiet. So you observed him from afar. Trying to figure out what was going on. And you finally came to a conclusion.

Caine had developed social anxiety.

Currently, you and Caine were sat together. Caine was quietly doodling in a sketchbook. Do you confront him? Or stay quiet?
