...I'm jumping off the merry-go-round at this point.
Looks like Yorkshire Tyke jumped off before you !! He probably decided that continued banging his head against a brick wall was self-inflicted !
I do NOT hold people responsible for becoming something they never intended;
I go along with that, in so far as alchoholism,and maybe gambling, can take hold from apparently innocuous beginnings.
I DO hold them responsible for their recovery once they know they have the disease.
So .. if they know, and continue without attempting to find a solution, isn't that self-infliction ?
I'm not going to get on this merry-go-round. S'long.
