Finger on the Trigger: You never hear from these people, except when texted, they respond with lightning speed. (Also known as “Lurkers”.)
Throw ‘Em a Bone: Your fear is if you contact these pests, they’ll text back fast and furious for hours. But really, all they want is one or two quick messages, and then they’ll settle right down.
The LOLer: Practically every single communication from these folks ends in “LOL”, or “lol”. Some texts read simply, “lol.”
The Silent Wall: This should be pretty much self-explanatory. Or not.
