Ok so, I can totally understand the monster's feelings in this show. They're dealing with all these humans that are ungrateful and don't appreciate what they have, and every episode they're telling these people, "Why are you so ungrateful when you already have everything I could ever want, which is just to be normal."
The reason I can relate so much to them is because 7 years ago I was in a car accident and now I'm stuck in a wheelchair because of it. Whenever I see able bodied people depressed, then I'm like, "Hey what's wrong with you? You have everything I could ever want, an able body, if I were you I'd be super extremely happy all the time." And when I hear about someone committing suicide I just wish I could have talked to them before hand and said, "Hey idiot! Wake up! It's not so bad. You've got an able body. If I was in your position I'd be elated! Don't kill yourself. You've got a lot to live for!"
