     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 now 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(成年人)I feared(害怕) him and felt bitter about him He seemed unhappy with me unless I got straight A's and

unhappy with my boy friends 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 worried.

     On the first day of my visit, we went out with one of my father's friends for lunch at an outdoor cafe.

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(挑剔的)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 so doing, I'm delighted

with my new friend. My dad in his new home in Arizona is back to me from where he was.
