Not particularly friendly, but polite, quiet...mostly. You'd gotten used to the screams at night for a couple of months. Your new neighbor was attractive, but he seemed very withdrawn. Okay, so that was better than some teenagers with addictions from the floors below. You rarely saw him, but those rare and random glances made you feel strange. Sometimes he liked to stare. As if observing, ready for something to happen. But nothing happened. There was only curiosity on both sides.
