Plastic knife

I am trapped by life Grab my plastic knife Stab my back it's fine Half the matchstick's ice What do you expect to happen when it's all so shielded Plastic knives can't hurt you don't feel threatened when I wield it Generation untrained for danger risk and conflict Few succeed when freed after 18 years a convict Soon you will collapse Under just your weight Too much time's elapsed You have sealed your fate Soon you will collapse Under just your weight Too much time's elapsed You have sealed your fate I am trapped by life Grab my plastic knife Stab my back it's fine Half the matchstick's ice
