"I had no idea that he was going to write that, but I've always believed that insecurity was what would keep you always in your innocence, no matter what the business did"

In this quote, Sally Kirkland is assessing a piece of composing by someone she is familiar with, and her reaction reveals a much deeper consideration on the nature of insecurity and its role in keeping innocence. The quote touches upon a number of essential themes: surprise, belief, insecurity, innocence, and the impact of the broader world, represented by "the business."

To start with, Kirkland reveals surprise at the material of the writing. She "had no concept" that the individual would compose something of this nature, recommending it was unforeseen and possibly exposing in a way she hadn't anticipated. This surprise indicate the diverse nature of individuals and their ability to produce work that can generate new insights or feelings from those who understand them well.

The main style of her reflection is the juxtaposition of insecurity and innocence. Kirkland suggests that she has actually constantly thought insecurity acts as a protective barrier that maintains an individual's innocence. Here, insecurity is seen not necessarily as a negative characteristic, however as a state of being that preserves one's purity or naivety. It suggests a particular vulnerability that keeps people grounded and possibly more genuine, preventing them from becoming jaded by the outdoors world.

The term "the business" most likely describes the show business, which can be severe and unforgiving. In this context, innocence may indicate an unspoiled point of view, available to new experiences without being tainted by the cynicism or control often found within competitive fields. Kirkland's assertion recommends that preserving a certain level of insecurity can prevent one from being fully consumed or damaged by the more negative aspects of business.

Overall, Kirkland's quote is an introspective musing on how vulnerability can work as a defense against losing one's inherent innocence, even under the pressures of a demanding and typically ruthless industry. Her belief highlights a nuanced understanding of human feelings and the intricate interplay between personal dispositions and external influences.
