If you go back and read what I posted, you'll see that I acknowledged the nebulous nature of an outside perspective of happiness, i.e. Poor Little Rich Girl. I acknowledge that you often can't tell; some people seem like little balls of sunshine externally, but they're dying inside. Some people look like Frankenstein outside but they're happy as a lark internally. Because of this, I included how I distinguish people who seem to be happy. One of my ways for doing this is by noticing how willing and how a person talks about these dark moods. Isn't this what the thread is about? I think it's curious that when I get "dark" about happiness there's an unwillingness to go there. Is there a such thing as the downside of up?
I'm not talking about being a resilient person and bouncing back when life get's ugly, that's an admirable trait. I'm referring specifically to those happy people who are almost bobbleheaded in their happiness. If one of these "happy" people consistently blows off talking about darker topics, then yes I think it's shallow. The financial crisis example of people blowing it off, whenever it comes up in conversation. I've been around people that say "Let's not talk about this!" and there never seems to be a good time talk talk about more substantial things. I also said that I may not be around them when they do and I may not have the complete picture.
This is not some minority or thin slice of happy people, although I never implied it was the majority either. I encountered a lot of this in college, but I suppose it's to be expected with younger people because they haven't experienced much. Now when I encounter it, it strikes me as willful ignorance towards life's unpleasantness. I believe this is called staying in one's ivory tower is it not? Evidently it happens often enough for there to be a sociological term to describe it.
