reptilian invaders

Two small lizards live in the tree outside my office. They scramble around the sidewalk and bolt into our reception area every chance they get. I'm not sure what they're after. Maybe they find my office mate's unreasonable fear of them amusing. I find them cute and interesting and would like to touch them but I am dissuaded by the humbling if not slightly embarrassing prospect of having to explain a lizard bite to a medical technician or my boss.

Instead I watch them from afar and leave them Chex Mix offerings on our front stoop.
