That’s still so broad! You could say that not having nutritionally complete cold gruel and water for every meal is a treat, or that choosing the healthier but more expensive option on a lunch menu is a treat. Or that choosing to live in an apartment where you can cook is a treat.
I think that’s the hard/personal part. Don’t get me wrong, I fully believe that the ability to cook for yourself where you live is necessary but we both know it’s a luxury for some people.
