Believing everything your child does wrong is entirely down to the company he or she keeps.
We are all a little weird and life's a little weird, and when we find someone whose weirdness is compatible with ours, we join up with them and fall in mutual weirdness and call it love. Time is too slow for those who wait, too swift for those who fear, too long for those who grieve, too short for those who rejoice, but for those who love, time is eternity. I've fallen in love many times... always with you. What I need to live has been given to me by the earth. Why I need to live has been given to me by you. Love is just a word until someone comes along and gives it meaning.
We learn in the past, but we are not the result of that. We suffered in the past, loved in the past, cried and laughed in the past, but that's of no use in the present. The present has its challenges, its good and bad side. We can neither blame nor be grateful to the past for what is happening now. Each new experience of love has nothing whatsoever to do with past experiences. It's always new.
