To some people the presence of a lizard would be obvious. They would see it, right in their path.
I am often oblivious to lizards. I don't remember that they exist, if one hasn't just run up the wall.
Are we obvious to lizards? If one runs, he probably saw me moving toward him. They come to our compost bin to eat bugs. I bring new scraps from the kitchen. Out in my yard, sometimes lizards can seem to be oblivious to people, or to cats, or to roadrunners.
As the parenting of children goes, it is good to lean toward what is obvious, and to avoid being oblivious.
