I was taking my 4 year old granddaughter on a little bus ride when she said,"Nanna! Did you know that tortoise and turtles live to 100!! "Yes" I replied. Then came, "it's because they walk really slowly...... and because you walk really slowly now, that means 'YOU! will live to 100!!....I will walk really slowly with you and we can be 100 together!!....(secretly wipes tear from eye) Oh, the joy this little one gives me is second to none!!
