An Afflictive Boil on My Ass

Afflictive:  That causes physical or mental pain.

"Oh, it's not the physical pain I'm worried about.  I can handle the physical pain.  It's the mental pain that would kill me.  They'd take me off there in a body bag."  Little Westside Jonny, adamant that he wouldn't survive a night on a little, tiny island in the middle of a boggy lake in the middle of the Amazon.  (I was just as adamant that I could do it.  But then again I've always been a liar.)

The Buddha says that the third type of suffering that can torment us - after outright pain and the cessation of pleasure - is of the afflictive variety.  Discovering the three sources of our suffering is The Second Noble Truth - here we learn that afflictive emotions contaminate our behavior in two distinct ways, one that needs to be expressed and one that is best left unsaid.  An example of the former would be revealing a painful episode in your past that makes you wary of close personal relationships.  An example of the latter would be walking up to a friend and saying: "Your girlfriend is hot - I'd like to sleep with her" or maybe mentioning to an irritant in your morning meeting: "Your are a boil on my ass."  

Neither of these need to be said irregardless of how much you would like to say them.
