I believe it may be possible for a few masochists, but not for the great majority of people. For example, let's imagine I decided to start beating the shit out of f00 on a regular basis. Imagine I began to systematically destroy all his clothing, microwave all his CDs, burn his space opera novels, and set the chinchillas loose inside his computer. Now, imagine that I'm not doing this out of some sort of mental illness, but out of sheer malice, a la The War of the Roses . Maybe for a little while, but after a bit, I can guarantee that love would turn into a psychotic blitz of well-deserved hatred.
Some people say they like animals because animals show unconditional love.
Again, I believe this is wishful thinking. If you have a loving, loyal pet dog, and every day, you kick that dog and screech at it, eventually, the dog will either run away or try to tear your throat out. If there ever was such a thing as unconditional love, I think survival of the fittest has been doing its damnedest to breed it out of our systems. The mall is almost always completely dead on Monday mornings. Anyhow, when I finished work, I meandered over to the fabric shop.
