Abaye & Rava argued over a balcony their entire lives.
and nothing, not something written on parchment or beast could sever their relationship.
(ongoing dispute between Abaye and Rava, about a paticular balcony, is described as going on their entire lives. hence the two old men & a balcony. Statler & Waldorf... they are permanently connected to each other with this to-ing and fro-ing. Unlike a married couple who are seeking a divorce. later in the page discuss that divorce has to be a written statement, and debated if it has to be on parchment or could it be written on a living creature)
