Dear Grand Daughter
I don't know if I will still be there when you get a chance to read this letter.
Things must have changed a lot by the time you read this.
I am an old man already, and belong to a different time. In our era, large and extended families loved together and loved each other. However, I already see large families breaking up and everyone being very individualistic, something I detest.
However, I have seen some amazing changes take place in front of me. I saw the development and growth of Radio, Telephone, Airplanes, Movies and TV! And I can't imagine the things you would see in your time.
Just remember one thing my love, change is the only constant in life. Never feel bad about it! Embrace it and you will be successful, if you avoid it, you will only Perish
I hope you find this letter in a time and place where you feel the happiest and I only wish the best for you
Yours truly
Your Grand dad
