Cockroach crisis

bird watching, dog walking, baby sitting but why no cockroach watching, eh? you know it can be just as engaging as the rest. try it. for example me, i was watching this tiny cockroach, well not so tiny- say, adolescent cockroach- delicately crawl on the edge between the floor and the bathtub. the poor thing sat nibbling presumably another poorer thing. then i intervene its little feast. i run my index finger one feet above the roach, creating a majestic little scary shadow for it, which is following its tiny little foot steps. it was fun, watching such a puny little insect distressed by a giant little me. i am a sadist. also, as u can very well infer, have no life! anyway, so i wave my index finger above it, following horizontally, wherever it moves. the roach is sensing an imminent death knell. hopefully. so after wiggly-waggly-woo, it stops moving. stoned. now i am confused. i could not have killed it from a feet high. and i possess no laser powers. what happened? but the roach sits so still, silently. i mean still. just still. it cant shout. can it? well whatever. but here it is. unmoving. did i give it a heart attack? then i wasn't sure if they have a heart. so now i bring my finger a few inches nearer to the roach. and then i distinctly see the bastard quiver. i am very angry now. it wanted to fool me! how dare it! i am angry. should i kill it, or should i just follow along the lines of non violence? i was so close to a real "to be or not to be" dilemma. here's my Claudius cockroach... but I hear the roach scream "run, run, run while she plays Hamletta! yo Dirty Mary, when u shoot u shoot...don't talk!"
