"Polytechnic" is a word in ENGLISH

The rain spun in the yellow arc lights over the café parking lot. It was empty inside, except for a fat Negro woman whom I could see through the service window in the kitchen, and a pretty, redheaded waitress in her early twenties, dressed in a pink uniform with her hair tied up on her freckled neck. She was obviously tired, but she was polite and smiled at me when she took my order, and I felt a sense of guilt, almost shame, at my susceptibility and easy fondness for a young woman's smile. Because if you're forty-nine and unmarried or a widower or if you've simply chosen to live alone, you're easily flattered by a young woman's seeming attention to you, and you forget that it is often simply a deference to your age.
