First, our local Aldi has had frozen deep fried Twinkies lately.
I tried a small taste of a deep fried candy bar a few years ago and almost went into sugar shock, I don't understand how people can eat something so unbelievably sweet. I don't eat Twinkies in the first place (although I do like Ho-Hos & Ding-Dongs).
On the main topic of your post, I've found that some people are very "comfortable" being miserable.
When they complain about their situation and you offer them easy to implement advice to change their situation, they either ignore you or take offense.
You can only help those who are willing to be helped.
