Laravel为不同的页面提供了未定义的变量错误？

so I'm having an issue with a laravel project and it makes no sense to me why this is happening, so maybe someone out there has experienced this.

In my home page, I load a partial, we'll call it: _homeContent.blade.php. In the controller for the home page, I am pinging an API, gathering data and returning it to the home page, as a $quotes variable.

So:

return view('home', compact('quotes'));

In my view, I have the loop:

@foreach($quotes as $quote)
    I do my loop things here.
@endforeach

So that works fine, no issues, the data is coming in as I expect it to. Further down the page, I have a link to another page. Just a standard a href="/my-about-page" for example. When I click it, I get an error that says:

Undefined variable: quotes(View: /my/path/here/_homeContent.blade.php)

Question is: Why am I getting this error on my about page, telling me that there is an undefined variable on _homeContent.blade.php. I was just on the home page and it worked, I leave the page, and it breaks the next page.
