Why Are You Smiling?
The spider smiled at him with a full human grin. Some part of Hu thought it might be mildly less terrifying if the spider were larger than the walnut-sized things before him, but he really didn't want it to be larger, and besides, he would be terrified either way. Perhaps terrifying wasn't something that could be gradated.
"What.... Do you... want something?" The spider continued to smile. It had crawled down the cafeteria wall into Hu's line of sight as he chewed the second bite of his dry turkey-havarti sandwich.
Hu looked around. The rest of the company break room was empty except for the vending machines where he'd gotten his unexciting lunch. He looked back at the spider which, despite his fervent hopes, had not vanished or stopped smiling. "Why are you smiling at me?"
Without warning it sprang at him. He flinched away so hard he fell, and still it landed on his temple. "You'll never get anywhere in this company if you don't ask better questions," came a disturbingly resonant voice (resonating how?). "If you had teeth these fine, you'd be smiling too. So then, where did I get these teeth?"
And with that, it was gone.
