Never go into a chatroom with two people in it.

Why? Person A and Person B are already bored with eachother. Person B doesn't want to leave Person A all alone, so Person B waits until Person C (that's you) comes along.

That's when Person B makes his move. He bolts from the chatroom, leaving you (Person C) and Person A all alone together.

Alone and bored. Alone and waiting for a chance to escape. Alone...and waiting for Person D to come along and replace you.

Innocent chatters of the world [wide web]: Don't let this happen to you.
