SJs suck cause
#1 They can't see that what their doing makes no sense cause their only doing it cause they were almost programmed at some point to do it and so never have really brought it inot their being it just sits there like a limp appendage.
#2 Some people build junction on their rail lines. SJs only ever seem to build branch lines. there's two results 1 and 0. There is no grey!!
#3 They usually want to be free of their own shackles and so resent others for being bereft of such things whilst failing to reconcile that it is only themselves they have to blame for that aspect of their predicament!!
