Location over Emotion
Typically, during a performance, Alan chills somewhere near the back of the stage, kind of disappearing while holding everything together, quietly. This behavior also holds true for Alan in other circumstances parties, at the bar, in restaurants, etc.
This is not to say that Alan is inattentive, but I was pretty damn surprised when he came over to my place one night, got up from where he'd been sitting, walked over to where the DeVore gibbons stood, got down on his knees before them, gave a sideways glance, and commented:
"You've got these things perfectly placed, all lined up along the floorboards at precise angles. Did you use a protractor?"
