That is going to happen to you at least once a week for the rest of your life.
Someone got on my case last week because I sold a child a "sad" book. The book was Charlotte's Web. Is it sad? Yes.
Is life going to contain sadness? Also yes.
And by learning to deal with it in fiction you learn to deal with it in life.
But some people want to be swaddled children for all time.
Kept away from anything that might bring them a moment of discomfort, introspection and learning.
Ain't healthy.
Charlotte’s Web is a great book, I loved it when I was a kid.
Charlotte’s Web was sad but it ended with generational renewal, her Children all with her mother’s ability to speak and spell. Death wasn’t the end. The person who got on your case was a simpleton!
They didn’t dumb the movie down either!
