Quote from : City of Glass Book

It was Eric's voice not Simon's, on the recorded message. “Ladies, ladies ” he said. Though it was the millionth time she’d heard the recording, Clary couldn't help rolling her eyes. “If you've reached this message that means our boy Simon is out partying. But please don’t fight among yourselves. There’s always enough Simon to go around.” There was a muffled yell, some laughter, and then the long sound of the beep.
