"I do not speak with my sister on the phone."
Translation:Io non parlo con mia sorella al telefono.
I put "Non parlo con la mia sorella al telefono" because I had made a mental note that the possessive always needs an article before the possessive word. I kept getting dinged for forgetting that in other questions, and now I'm wrong on this one because I did include it! Can someone help me explain when you need to say "la mia sorella" and when you can just say "mia sorella"?
