It's just unrealistic and a very obviously dishonest way to frame the story. No child is going to come up with an idea like this on their own. A vague notion of wanting to help the homeless maybe, but not hey mom lets use my allowance to buy these specific items to put in goodie bags that we can then distribute to all the homeless and lets make an announcement video for social media where I read this script I wrote that says "I just wanted to do something from my heart".
