Okay, "SIMPLE" is a very broad term! To give you the best answer, I need a little more context.
What is it about "SIMPLE" that you'd like to know or discuss? For example, are you looking for:
- A definition of the word "simple"?
- Examples of simple things?
- A discussion about the concept of simplicity?
- Something else entirely?
Please tell me more about what you have in mind!
