Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there
a few years ago, and I was eager to see his new place and meet his friends.
My earliest memories of my father are of a tall, handsome, successful man devoted to his work and family,
but uncomfortable with his children. As a child I loved him; as a school girl and young adult I feared him and
felt bitter about him. He seemed unhappy with me unless I got straight A's and unhappy with my boyfriends if
their fathers were not as "successful" as he was. Whenever I went out with him on weekends, I used to
struggle to think up things to say, feeling on guard.
On the first day of my visit, we went out with one of my father's friends for lunch at an outdoor café. We
walked along that afternoon, did some shopping, ate on the street table, and laughed over my son's funny facial
expressions. Gone was my father's critical air and strict rules. Who was this person I knew as my father, who
seemed so friendly and interesting to be around? What had held him back before?
The next day my dad pulled out his childhood pictures and told me quite a few stories about his own
childhood. Although our times together became easier over the years, I never felt closer to him at that moment.
After so many years, I'm at last seeing another side of my father. And in doing so, I'm delighted with my new
friend. My dad, in his new home in Arizona, is back to me from where he was.
