So here I am in Texas once again visiting and helping to take care of my granddaughter who will not be 2 years old until August, and today when I laid her down on the diaper changing table to put a fresh diaper on her...she looks up at me and says: "Knock, Knock." and I automatically said: "Who's there?"...and she said: "Amelie, Gran Gran!" My not yet 2 year old granddaughter already can tell a knock, knock joke. Evidently her cousins which she has been playing with all this past week taught her about knock, knock jokes...but I am amazed that she remembered and shared her knock, knock joke with me. So now I can't stop smiling or thinking how blessed I am to have this little angel call me Gran Gran!
