I have reason to beleive that there are very few real people left, and the rest have been taken. Taken by a virus, taken by something beyond their control, and now it is controlling them.
You may be refering to something completely different, but when I was younger I think I could relate to this sentiement. Generally I felt like a lot of people around me had some sort of mental block where they couldn't
confront their problems or emotions, this especially applied to adults. They just had this serious demeanor, and yet they never approached any serious issues.
As I got older though I think I realized that it's not that they couldn't
talk about their problems it's just that they wouldn't
; there's nothing controlling them. Acting serious and not talking about their problems is just the way they've learned to cope, it's really sort of an "out of sight, out of mind" mentallity. My way of coping with issues was to be non-sequitur and keep a humorous demeanor while still trying to approach any issues/emotions head-on.
