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