I don't believe in love. Let me explain about my lil tis and tat here..
Let's suppose that there's a white snake right in front of you. Now the attributes of that snake are 'long', 'white', 'creepy', etc...
It's now fair to say that the first two said above 'long' and 'white' can be surely guaranteed as commonly shared attributes of that snake, however can the third one 'creepy' be also defined to be one of the attributes? No, it can be 'lovely' depending on the mindset of the observer.
Sometimes, the concepts that seem to be shared by everyone can actually vary from one to another, because we percieve things through the filters of our "Minds". So, as we can deduce from the examples above, one has to highlight how ambiguous and untrustworthy human minds are...
It is said that "Love" broods in the mind. But if the nest is so insecure and incoherent then how can the egg be sure to hatch out? As long as our minds are not something universally standard and common, we can't highly confide in what they give birth to. They say that there's no happy love. But the fact is there's no unhappy love either.
I'm sorry to have taken too much of your time but this is why I don't believe in "Love". Nevertheless, instead I believe in "Friendship", which is not nursed in the mind but is born and grows in the logical thinking of our heads.
