I watched "A River Runs Through It" tonight and something in the movie touched me:

Reverend Maclean says that we all say to ourselves:

"'We are willing help, but what, if anything, is needed?' For it is true we can seldom help those closest to us. Either we don't know what part of ourselves to give or, more often than not, the part we have to give is not wanted. And so it those we live with and should know who elude us. But we can still love them - we can love completely without complete understanding."

Is that much like asking to "be granted the serenity to accept the things I cannot change, the courage to change the things I can, and to have the wisdom to know the difference" ?
