Rule reminder
Frame topics are prepositional or adverbial phrases placed at the left periphery that set the scene or domain for the sentence. Unlike object dislocation, they do NOT require a resumptive clitic pronoun: 'Di politica, non vuole sentire.' / 'A casa mia, si mangia bene.' / 'Per quanto riguarda i soldi, non ci sono problemi.'
