My dad's birthday

Today is my dad's birthday - 97 years ago he was born. Nearly a century. So long, so very long, and I didn't know him really at all. The family unit of four lasted until I was 8 and my sister was 5. I did converse with him from time to time over the years -- when I was in my first year of college we talked on the phone. In 1972, the year my sister graduated from high school and I had finished my junior year in college, he died. And that was 35 years ago.
