Robert called Flora's on her birthday.
R: Hello, Tim?
Nick(?): No.
R: Is Flora
there?
N(?):I'll get her
then he comes back
No, she's busy
R:Could you tell that her brother Robert called?
N: OK.
R: OK bye.
N: bye.
(hang up)
Robert said it was an awkward & brief conversation.
So if Flora did not get the message then tell her R did try to call her on her birthday.
