Like saying "reformed pedophile".
My nephew started drinking as a teenager. Born 1976, he died this year after destroying his organs as a result of being an alcoholic. I visited his apt around 2000. I saw beer bottles sitting on every surface, but realized...they were full of urine.
I laughed when I read an article saying he wasn't going to drink if confirmed Defense Secretary, I was like 'Sure you won't Pete' !
