Seeing aliens was normal for Bill

Bill saw aliens all the time, but he was a bank clerk not one of those men in black, so after the first time that he was laughed at, he kept it to himself. He saw mostly greys but he also saw less probable creatures that looked like octopuses, cuttlefish, and praying mantis. “Why can I see them,” he wondered, “when others are blind?” Bill feared it was only that no one can change what they really are.
