Love, a word rarely defined and mostly misunderstood because everyone experiences it differently. What one thinks is love, another may think is infatuation and vice versa.
Everybody has felt it at some point, be it for a person, pet or even a non-living object. One who has experienced it would bear William Shakespeare; the greatest advocate of love; witness as he compared love to a drug, it takes over all the senses in person. It intoxicates you to the core of your bones.
