Sarah posted a quote from Denis Waitley, which said: “Happiness cannot be traveled to, earned, worn or consumed. Happiness is the spiritual experience of living every minute with love, grace and gratitude.”

“Thank you to all the very special and kind people that took the time and trouble to send amazingly caring and supportive messages…never has a mother been more proud than the wedding of Eugenie and Jack, and again with my Beatrice’s loving wedding to Dear Edo. I am so lucky with my girls, and now the best sons-in-law,” she happily captioned the post.
