Sometimes, it's called a lack of maturity, which usually stems from disengaging from life rather than actively engaging with it. Interestingly, such kind of experiences can be a way for people to "build maturity" but what they end up doing is make a big deal out of it and chicken out.
Oh completely agree dude. This person is immature as hell and it's really annoying. They can't handle life but use many excuses to blame others or just not participate. It's sad because that's a lot of people in this world unfortunately.
Yes, the number keeps on increasing, especially with the younger generation. If only they could realize the long term consequences of their present flimsy actions!
