talk is not even cheap, its free. thats why

thats why we all could take words and use it as a weapon to defend ourselves at the expense of hurting others. all these while, it has become vulnerable. we have become vulnerable to words and the aftermath effects that it has taken on us. with every other words spoken, it either enhance or destroy us. but most of the time, words wear and tear us apart. we may not have realised it, but words, they are powerful. they are strong. they do harm. and they do kill. perhaps we've all been loose with our words, damages are done here and thereafter. if i were to rank the most deadly weapon that incurs no cost at all, it would not be biochemicals nor nuclears.
it would just simply with words spouted.
