Obsession

I wonder sometimes why people are so obsessed with love. Attached to it. We make and watch movies about it, we read, write, sing and make art about it, we get tattoos because of it (ahem... we all know who does that).  Mostly its romantic love, between two (or more) people, though it's certainly not the only sort of love. Why does it feel so good? When there is someone who just understands how you see the world, its refreshing, and you want to be around that person all the time. Being so close to another person, its like you share a secret with each other that no one else knows...
