Once Csongor was logged on to a computer it took him only a few moments to establish its IP address and a few moments more to snoop around the local network getting an idea of what IP addresses might be assigned to neighboring machines. So "checking his email" took only a few seconds, and then he was logged off and ready to go. He walked toward Zula, breaking stride as soon as he got within about a meter of her, and then turned sideways. For he had not approached her to talk, or for any reason other than to be in her presence. This had become his habit. Zula had grown accustomed to it. She felt better when he was there, just on the edge of her personal space. It appeared that he felt better there too.
