Friend?

Every day I ask Daughter #2 how her day was, and she tells me about kindergarten, that she went outside and took a nap, what she played, and what she ate. This was the play part of one conversation:

D #2: I played with dolls.
Tete: By yourself or with a friend?

D #2: With my friend.
Tete: Which friend, Pijus?

D #2: No, another friend.
Tete: Who?

D #2: Friend.
Tete: Well, what's her name?

D #2: I don't know.
Tete: How you can call her your friend if you don't even know her name?

D #2: (sighs) I played by myself.
