A slight commotion drew Kaa's attention away from trying to skirt the crowd. It wasn't an uncommon thing. No matter where he seemed to be, there were always a few desperate individuals grabbing coin purses to feed themselves. Of course it wasn't necessary for himself - his kind didn't need things like that. He could certainly appreciate the effort, though, and watched, grinning a bit, as the thief swiftly made her way through the masses of more fortunate people. They was away from the crime in a matter of seconds with no one the wiser.
There was no need to waste time even making the decision. He'd surely check it out, maybe congratulate them on a successful grab. He'd met many street-dwellers before, and most, he found, were quite entertaining. He was lucky he looked the way he did, childlike and scruffy, just like them. Well, excluding the wings and feet. It might return some semblance of normalcy to his life. Kaa couldn't fly like he used to, but pick-pocketing and such was still free game. Maybe he could forget about his own problems for a bit and worry about someone else's.
He made his way over to her excitedly, talons clicking loudly on the stone below him. He much preferred walking on stone than dirt. Not only was the sound pleasing, but some people didn't realize just how hard it was to get girt from dirt roads out of one's toes. Stopping just outside of the alley the thief had ducked into, Kaa gave a friendly wave to the... he looked at the kid. It was a boy, right? Cute for a boy, anyway. Young, yeah, but he couldn't place an age. Humans had such short lives, but he still couldn't manage to tell what age they were.
Thinking about age in that one moment, Kaa smiled at how he must look. A little boy, clothed in rags, human if it were not for the bird-like feet and giant black wings, folded and chained around his chest. Hm.. the boy, at least, had proper clothes, tattered and dirty though they were. It was only then he noticed the shiny coin the young thief held. "Oh, that's pretty!" he said without thinking, "That the one ya just took now?"
