Some reasons Peeta calls Annie:

"Annie, I think Katniss has some kind of life-threatening disease, I'm scared." (She was pregnant.)

"Annie, I'm so sorry to bother you but the baby moved."

"Annie, I just remembered – Finnick was the one who gave us Real or Not Real. It was Finnick." (Of course.)

"Annie, Primrose walked today!"

"Annie, next time you visit can Nathan please stop pretending there are sharks in the lake?"

Some reasons Annie calls Peeta:

"Peeta, do you remember how I sang to you in the Capitol?"

"Peeta, do you remember my wedding cake?"

"Peeta, I'm on my way."
