Hmm, i've been divorced twice, so maybe i'm not the best judge of what love is. Especially when I look back and consider the times I actually considered myself actually in love, and it wasn't my ex-wives, so ya maybe I need to work on that…
There's also different types of loves. After relationships, friends and family, I thought I had experienced them all, but then I had my daughter and learned of another type. And all types of love seem to be modular, as in they have some elements from another type. I've also found it interesting on how my idea of love changes as I age and experience different events. Also, I don't believe in love at first sight. That's just a crush. Being in love is something that is earned… Unless you count Kate Beckinsale. That was love at first sight.
BTW @Darth Tagnan; , you're really asking the pondering questions here these days. Just for fun, or are you having some introspective mid-life events?
