Shen realises, perhaps a beat later than anyone else would, that he's already getting impatient and short of breath just listening to the man. And he has no idea why. WHY is he so impatient with content people? Is it because he, himself, is not content? Is it because things need to be done and sitting about being content is nothing more than stagnation? He has no idea and that frustrates him even more.

"NNGH." Then, having sufficiently vented said frustration with that one semiverbal sound, he rubs his brow and sighs. "Forgive me, I.... perhaps I used to be someone who liked everything under control. I find it difficult to see how one can be... content in the face of so many questions. Absolutely everything is a mystery--where am I from? Why did I have sixty-three bladed weapons in my feathers? What happened to my feet?" He lifts one foot in a manner far to effortless for an ordinary being and then drops it again. "Why do I speak the way I do, think the way I do... I question everything and these questions... they drive me mad at times...."

He also has no idea why he's spilling his thoughts like this. Perhaps it's just something about this Iroh fellow that seems so trustworthy.
