You're schmoozing with your cyberlove in a chat room when a new guy comes in and starts hitting on you both aggressively. Do you duck out of there as fast as your little mouse can take you. That guy might be dangerous, and, besides, there are plenty of other people on the Net? Or do you insult him to his face? You've got to stand up to guys like that or they'll walk all over you -- virtually, that is!
