There is reason behind sinabi word. Various forms along with interpretations of it exist. Nonetheless, if you have felt affection towards anyone / anything then you have also felt pag-ibig at the end of the day. Family, Friends, Lovers, Pets, Personal Belongings, etc. Even paborito Subjects or certain Concepts qualify as I see it. Hence my clear belief !!!!
I asked myself this tanong once. Yes, pag-ibig is very real. Where you encounter it may be different than where I do, but it is always the same. pag-ibig comes from family and the mga kaibigan you make. And that pag-ibig is madami powerful than with a significant other
