It is simple, can you make it hard ?
If something is explained in detail with field specific terms it can be confusing and difficult for people to understand. Therefore its a great skill to be able to take that explanation and dumb it down into a common sense style description. Somewhat of a more difficult skill is to take a simple explanation and make it extremly confusing and so complex its meaning even gets lost to the person doing the explination. Can you do this, make a simple concept into a masterpiece of intellectual conffusion using the simple explination of what makes anything FREE ?
The simple explanation is that,
Free can only be something without restrictions.
Simple enough, how hard can you make it ?
Old dog: I would not be supprised to see something be made difficult, thats the easy part. And simple can be harder to accomplish because its not defined by anything other than not being complicated but still well understood. Depending on your audience thats near ( Near I say !) impossible.
