Lets role-play. I will be Me, you be the Village Idiot.

Me: Hai guise! I am going to kill everyone in the town, just maybe though. I think I will probably change my mind but I am not sure, so you probably should take every decision I make with a grain of salt.
Village Idiot: OTAY!!!
Me: I am not going to kill everyone.
Village Idiot: OMFG He isn't going to kill everyonem, praise the lord! We has been saveded.
Me: I changed my mind, I am going to murder everyone.
Village Idiot: Lulz, NO WAI!! I was thwarted, and are retarded. I should spread the word so everyone can seek c&c.
Me: Ehh, tell you what, I don't think I will kill everyone today, maybe tomorrow, but not today.
Village Idiot: But.. I just told everyone to hide, now your going to make me look stoopid.
(from way out in left field, KA yell's) Stafoo Village Idiot, you are an idiot.
