This is
a tough woman, quite strong-headed. She observes others, decides what
to do, and does it. Pleasing others and having a good time is not her
goal; she wants things be done. Depending on circumstances, she could
be very talkative, even argumentative, but could simply fall silent if
she chooses to do so. It's not going to be very productive to be
fanciful so as to trick her; better be logical and reason with her.
That way you show her your respect and seriousness.
