What really bothers me about humans is that we can't wrap our minds around some concepts. For example, when we try to think about the concept of nothing, and we have questions like, "What color would nothing be?" "What shape does nothing take?" "Can we live in nothing?" When nothing would have none of those questions in them. Because it's nothing. Nothing doesn't have a color, a shape, or a living being living in nothing, because it's nothing.
Confused yet? Or can you actually wrap your mind around it?
