do I say duplicity correctly in both situations below.
1. A girl who has a big crush on a boy but she is shy enough to express her emotions. Everytime when she talks with her friends, she always says that the boy is annoying, actuallly she doesn't think so(she has a big crush on him)----can I say at this time "your duplicity"?if not, do you have a better word?
2. A man who pretends to be nice to people seemingly but secretly talks negatively about those who he treats nicely.---is it duplicity?
