Why the "de" after rencontré when rencontrer takes a direct object?

Question

j'ai rencontré de votre mère....je l'ai rencontré  is correct so I don't understand.

Accepted Answer

Hi Leah, 
Thank you for bringing our attention to this as it is an error that I have now corrected -
J'ai rencontré votre mère
is correct 
or

J'ai fait la connaissance de votre mère 
J'ai fait la rencontre de votre mère

Answer

Hi Cécile,Despite the rule that penser takes the indicative unless used in the interrogative or negative, couldn't the phrase "je commençais à penser que je..." express sufficient doubt for the subjunctive to apply? John

Answer

Hi John,
You could, but the use of the subjunctive when not strictly required can sound  highfalutin and you could also argue that the doubt is dispersed by the fact that the speaker has now met someone.
I personally wouldn't have used it.
Bonne Continuation!
