I have learned that only two things are necessary to keep one's wife happy. First, let her think she's having her own way. And second, let her have it.
Being in a long marriage is a little bit like that nice cup of coffee every morning - I might have it every day, but I still enjoy it.
Love is always bestowed as a gift -freely, willingly, and without expectation. We don't love to be loved, we love to love.
