Funky, you know I dig you. Unfortunately duty called and many others picked up the ball and ran with it better than I could have. I don't think you can put emotions in the same category as say, bone density in terms of being able to test for it or say that it is "real". None of us can climb into another person's head and know, truly know why they do what they do, we have faith when a person tells us that they love us that they do, and we look for signs that they do, but we can never truly know that they do, we take it on faith.
I think there are many things in this life we take on faith as the manifestations could be interpreted in so many different ways. Or let's even say the idea of marriage, you want to talk about a leap of faith, will you love me, care for me, in sickness and health, till death do us part? I'd say going into that deal takes a huge amount of faith.
