This is a great reminder. We, all too often, take our families for granted by giving them the brunt of ourselves and the best to total strangers. Love your family and the strangers around you will see that and want to go home and love their families!
If you could only sense how important you are to the lives of those you meet; how important you can be to the people you may never even dream of. There is something of yourself that you leave at every meeting with another person.
