By the way, does the maid know that you had install web cam?
I told my maid already as someone told me that it is against the rules by not telling the maid that you are taping her activities at home when she is not aware.
I think she will do it again and again because that's her character. Oldster always say that once's character is formed since 3 years old and will last till 80 years old. Please be tolerant or else just fire her...
