I'm sorry for your loss, Apple. You will always have the consolation of having had a wonderful mother, and of doing right by her, especially at the end. "Closure" is getting to be a very glib word, but not when, as in your case, you did the right thing, and earned it.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
