XIV. Don't just type "yea" to your friend when you have nothing to say. I understand the flashing IM is intimidating, and a lot of people need to have the last word, but the "yea" is basically IM code for: "I have lost a lot of interest in this convo, and was kind of hoping we could just drift apart peacefully."
or smiley faces... lol just say you hate me and are just trying to be nice.
