This is a funny topic pero totoo. me, my policy is "STRICTLY NO". di pwede to anyone even to my close friends kc i treat my dvd's as my sacred priced possesions. ala hiram hiram kc baka mawala or magasgasan. normally, other people are not careful about any stuff especially kung hindi sa kanila. Just say no and tell them your valid absolute reason right away. for sure maiintindihan nila yun. you're not being madamot. you are just protecting your stuff from potential theives (kunyari nawala nya or nakalimutang isuli or hiniram ng friends nya hanggang di na makabalik) I say this based on experience! kaya warning narin to sa mga kaberks natin dito.
