Magpie,
That pretty much sums up my experience with people suckered into Landmark. There's a sort of vacuousness, dull and tired look, a sort of smugness that they know something that you don't (even if, like myself, have been conned into the Forum), conversations that mean absolutely nothing, a disinterest in current affairs or even friends' news.
Sorry, I don't want to
