They are different
- A description is an exhaustive, dry representation of a concept. It is what education uses. It is better to add too much information, rather than being incomplete. Description have a standard format, structure (inside, outside, etc.). Descriptions are wordy translations of what can be transferred using an image in one second.
- Stories get to the point. Anticipate the audience's obvious questions, take into account the audience context, build on what the audience already knows, use surprise and tensions, and a flexible structure that is not always the logical, standard one.
