I disagree with this totally because keeping people too soft does them a disservice (can get them chopped up/killed/taken advantage of/or even in "safer" circumstances cause them to be more dependent people rather than relying on themselves). Also, I think allowing people to be too soft ironically DECREASES their empathy for other people's suffering. If you aren't informed of how hard life actually is, you might not even have the proper context to sympathize with people who have REAL PROBLEMS because you're so wrapped up in whiny petty shit.
Trust me, Fs will still be always seem a tad naive, even with hardening up and life skills. LULZ.
