Damn straight it's possible. Just as sure as the sun will rise, love can, and will, find a way - even if it is via a modem. The bottom line is love ain't easy, regardless of where the two people meet. Whether in the real world, or in cyber space, sometimes it's heaven and sometimes it's hell. But that's life - deal with it.
Love is funny, especially when it's discovered through a modem.
There's no explanation other than love. Keith and Sue didn't meet in a chat room, they were set up in one. There may be trouble on the horizon. Vic and Heather were like Romeo and Juliet with a twist. At least no one died.
