Think of a day that you will never forget. A day that your life changed somehow. A child may have been born; a loved one may have passed; you were fired from or accepted into a job; began your first day at work, college, university or volunteering; were diagnosed with an illness or told some bad/good news; celebrated something, or visited a place you'd never been before.
Today may be an ordinary day for you, but in someone else's life, for someone you may or may not know; today is one of those life changing days they will never ever forget.
So, be kind to strangers. That woman on the check out who seemed a bit short with you may have just lost her job. That man who looked at you and smiled at you, may have just been told he doesn't have long to live. You just don't know. But one thing is for sure, and that is today is someone's life changing day.
We each take our turn for events, and your day will come along again soon enough. Just think of how you wish the world to be for you on that day, and be like this today.
