As it's Halloween, I post my often reprinted story once again...
David B. Riley
He couldn't tell for certain if no one had seen him, but there weren't any sirens screeching through the night. Kal opened the hatch and climbed down. So far, so good. He hurried across the park, then stopped by the statue of some guy on a horse. The house was just across the street. He looked right, then left, then scurried across the open area and slid under a tall bush. So far, so good.
He climbed out from the bushes and strutted boldly up to the front door. A slight sense of dread was trying to overcome him. He fought it off. If only humans weren't so darn big. He reached the porch. His antennae were vibrating from the music inside. At least they were home. He readied his ray gun and pressed on the door bell button. He liked the pleasant chiming sound it made and rang again.
Slowly, the big door opened and he peered up at a human female. He raised the weapon. “Give me Earth food now,” he ordered in his most forceful manner.
“Oh, George, come quick.” It's summoning its mate, He prepared to fire. Then, a human male arrived holding a tray of candied apples.
“He's so cute. Just like a little space man,” the female said.
“Less talk, more food,” Kal ordered.
“Of course. You've got a long way to get back to your planet,” the male said. A very sensible individual.
“I just made them,” the female stated.
He placed one in his loot sack. It was so big he decided not to ask for more of them. He didn’t want humans to think his kind were greedy.
“Good night.” The male closed the door.
Kal scurried back across the street. A small human female wearing a mask ran towards him. He readied his ray gun, though she looked young and harmless..
“They got candy apples?” she was asking.
“Yes. They look good.” He held tightly to his sack in case she tried to grab it.
“I'll go get me one.” She trotted across the street. Kal holstered his weapon and watched in amazement. Without any weapon, the young female obtained a candy apple from the elderly couple. Kal reasoned the mask must be frightening to humans. The young female stood at the edge of the sidewalk and waived at him. “Happy Halloween,” she yelled.
