I'm tired of dealing with my two-faced co-workers and capricious boss.
我讨厌跟那些虚伪的同事和善变的老板周旋。
two-faced 直译过来就是：“两面的”，这个短语的正确意思是：“虚伪的”。因此，当美国人说"I'm tired of dealing with my two-faced co-workers and capricious boss."时，他/她要表达的意思就是:"I hate dealing with my hypocritical colleagues and fickle boss."、"I'm sick of mingling with my disingenuous workmates and variable boss."。
