[Tex/LaTex] Left marginnote does not work

Question

I badly need to have marginal notes on the left margin.
The command \marginpar does not work.
Supposedly, \marginnote works, and this needs the marginnote package.
OK, I tried, but nothing happens.
Here is the LaTeX code:

\documentclass{article} 
\usepackage{marginnote}
\begin{document}
This is normal text. 
\marginnote[left]{right}
\end{document}

Unfortunately, anything I put on the [left] field is ignored.
Any help would be greatly appreciated!

\reversemarginpar is used to switch between the "traditional" right-side margin paragraph and a left-side alternative:

\documentclass{article}
\usepackage{showframe,marginnote}% http://ctan.org/pkg/{showframe,marginnote}
\begin{document}
This is normal text. \marginpar{right} \par
This is normal text. \marginnote{right}

\reversemarginpar
This is normal text. \marginpar{left} \par
This is normal text. \marginnote{left}

\end{document}
