Just as some people have better control over their bodies, and therefore are better at sports, I believe some people have better control over their thoughts. But to think that love is something that happens to you with no effort on your part, is to resign yourself to a life of short-term love only. And I don't know how that equates to love within the family. I know I have a brother I find less than lovable, and sometimes my kids are not lovable for years on end. How does how I feel about them fit into a definition of love. Romantic love, invented in the middle ages to keep younger sons of wealthy families busy so they would not attack their older siblings' property, was never meant to be married love. It was love from afar of an older married woman.
