Rudeness, aggression, rage, paranoia, and addiction to crises make a wretched brew, make it difficult to help or even be close to someone you care about. If these vices grow they too easily creep past unpleasant and become unacceptable. When intolerable behavior will not be mended you must separate yourself from it or risk your self-respect and sanity.
But how easy it is to confuse the mad with the bad! If a loved one drifts into irreality and you mistake it for sheer cussedness you risk abandoning the sick instead of healing them. Oh, but how easy too to confuse the other way around! If you coddle a jerk, you hurt yourself and only invite more.
No stones mark these bounds, only nuances that weave snag by fray by twist into benightedness. Our fevered culture and medicine respond clumsily, blind to the flowering of illness. Not until madness blooms into destruction does the penny drop. Until then we can only watch and grieve as a fair child unravels in fits and starts smeared across the slow passing of seasons.
