Listen her, some bosses need buttering , do that also , she may has other aim to force you to quit this job and the boss want to hire his friends or relatives. If you quit she will win and you will lose. If she or he makes you angry with work, that mean she rule on you. Her aim to make you nervous and frustrated , if you be then again he won here too. SO keep patient after all you are Boss there later, but learn this lesson and don't rule your other juniors.
