Where is it written that we must be the same age as the one's we love? Is love stronger between two twenty year olds than it is between a twenty year old and a forty year old? I say no, love is love no matter what the age is.
Love can grow no matter what age we are. Does that mean that a parent's love for their four month old is not as strong as with their five year old? No, because it is love in the purest form. We put too much weight on ages in a relationship these days and not enough on what is important in relationships, LOVE!
As always, may the Force be with you.
