I'm assuming that is your mom and dad, that is a gift. Seeing your post brought tears to my eyes. My mom was a letter writer. Even when I was just a few hours away in college, she would send me a box of stuff or newspaper clippings from my hometown but she ALWAYS included a letter she had written. She wrote beautifully whether it was half a page from her steno pad or a 2 pager running down everything going on with the family. In 2005 she began having memory issues and my worst fears were confirmed within a year. But even then, she still remembered to send birthday cards, to me, my wife, my son. And in each she always put a small personal note. One of the worst days of my life was the first year I didn't get a birthday card from her. She did send my wife and son one that same year for which I am grateful. That was the last year we ever received mail from her, 2009. I watched Alzheimer's slowly take her from us for nearly 8 more years. I'm 54 now and I still have the majority of those letters and cards she sent. I wish I had them all but in my stupid youth some got lost along the way.
Cherish that she took the effort to position the phone so it would be at the corner of the page so that she could write you a personal note in her very own hand. It's beautiful.
