There is nothing wrong with simplifying concepts for newbies, but use one that fits the language.  There is nothing 
difficult with either the sticky note analogy or the pieces of paper and a string analogy.

Teaching someone that Python variables are containers is a massive fail.

There's also the whole class of programmers who only know one language, or only a small handful of related languages 
that all pretty much operate the same as far as variables are concerned.  The simple analogies is also helpful for them.
