I've been thinking about this lately myself. Love for me is undefinable because I love many people in many different ways and for many different reasons.
I love my husband with an honest pure love. He is the one person in the world I trust beyond reproach.
I love someone else because he is wonderful, caring and a perfect playmate. His heart, soul, and mind (not to mention body

) speak to something deep within me, someplace where the primal urges hide
I love someone who never loved me because he taught me soooo much about me. He taught me that I should spend less time wishing and more time making things happen.
I love friends who make me laugh, sharing their joys and sorrows. They make me feel warm and cared for.
I love my children with no strings. I may run out of patience, or energy but my love for them is unending. Be they doctors or be they mass murderers they will have my unconditional love.
Someone once said love is not the way you feel about a person, but how being with that person makes you feel about yourself. I think this is true. All of these lovers have made permanent changes in my life. Their influences on how I view myself, how open I leave my heart, and the world in general, will forever leave traces on my heart.
Damn...see now you know why I don't usually think, I just feel...and go with it!
