they're effectively externalizing responsibility for managing their emotions to their environment, by equating "me not being upset" with "the environment not being upsetting"
this is understandable, for small children! for adults, not so much
some want their world to be soft
however, this is unreasonable; i'd say, "so long as scarcity remains", but lets be real, even after that, there will be people who insist on being upsetting
so, if the world cannot be made as soft as you'd like your internal environment to be, what is left?
to toughen up.
