[Whatever you might be doing -- shopping, having a cold one, playing a definitely honorable game of cards that in no way includes cheating, whatever -- abruptly a purple chameleon just over the height of three feet appears. Did he pop in out of no where? Nope, it's just camouflage, but he might as well have been invisible until just down.

Regardless, he acts like it's no big deal, and addresses you politely like nothing even happened:]

Good day.

Might I trouble you for a small favor? I am attempting to experiment with this camera, and I found you photogenic.
