Dear Mom,
I have missed getting to see you. Since it is summer, I was reminded of all the wonderful times spent in my childhood yard. I loved sitting in the grass with watermelon juice streaming down my face. Those were truly the days. I remember blowing bubbles when I was seven and chasing butterflies in our little half-acre slice of Texas. This place was so important to me, because it taught me to enjoy the simple pleasure of life, and enjoy the gifts of nature. I have thought about our old house many times, and I am so thankful for my wonderful childhood I spent there.
I love you and thank you so much for all you have done for me,
Your Daughter
