Lies [Part 1].

I don't believe there's such thing as a "white lie".
This is what Dictionary.com says:

white lie 
–noun
a minor, polite, or harmless lie; fib.

And this is the example that they provided:

An untruth told to spare feelings or from politeness, as in She asked if I liked her dress, and of course I told a white lie. This term uses white in the sense of "harmless." [First half of 1700s]

Seriously, is there even such thing as a harmless lie?
Let's use the example that they gave.

By not telling the woman that the author did not like her dress, it just leads her to think that the author likes these kind of things.
In the end, the woman will be misleaded, which could lead to many things, like money wasted, relationship between the author and her becoming worse etc.
So, in the long run, the lie would be harmful.
Thus, it is not harmless, which contradicts the meaning of a "white lie".

I'll continue with Part 2 later.
