Hi Aurélie,
I notice a few people have asked the same question about the sentence - Tu lui as parlé' being translated as 'You talked to her' but parlé not agreeing with a feminine ‘lui’. You have said that the past participle doesn’t agree with an indirect object pronoun, and refer people to the advanced lesson: Special cases where the past participle agrees... However that lesson only talks about direct object pronouns and doesn’t actually say that the past participle doesn’t agree with an indirect object pronouns. I wondered if - for completeness and clarity - you could add that to the lesson, if it is not covered elsewhere. Many thanks.
