Brittle
"Brittle," yes, that is ye right word, "brittle" hard and fragile and subject to shatter, living in dread of that single impact, from within or out that starts the cracking that will not stop, that spreads so fast fragments can find no names, no way to join, repair, but fall each alone, a person's remnants, with razor's edges, but not a person but how came she so cold, how fear frozen, how desperate of concealed ambition, how horrified in pitiless envy's rage, how sure of nearness of nonexistence? "brittle" gives this riddle a new disguise, she can't bear the gaze of her own sad eyes
