21. In the depths of my memory, many things I did with my father still live. These things come to represent, in fact, what I call __21__and love.I don’t remember my father ever getting into a swimming tool. But he did __22__the water. Any kind of __23__ride seemed to give him pleasure. __24__he loved to fish; sometimes he took me along.But I never really liked being on the water, the way my father did. I liked being __25__the water, moving through it, __26__it all around me. I was not a strong __27__, or one who learned to swim early, for I had my __28__. But I loved being in the swimming pool close to my father’s office and __29__those summer days with my father, who __30__ come by on a break. I needed him to see what I could do. My father would stand there in his suit, the __31__person not in swimsuit.After swimming, I would go __32__ his office and sit on the wooden chair in front of his big desk, where he let me __33__anything I found in his top desk drawer. Sometimes, if I was left alone at his desk __34__ he worked in the lab, an assistant or a student might come in and tell me perhaps I shouldn’t be playing with his _35__. But my father always __36__and said easily, “Oh, no, it’s __37__.” Sometimes he handed me coins and told me to get __38__ an ice cream…A poet once said, “We look at life once, in childhood,; the rest is __39__.” And I think it is not only what we “look at once, in childhood” that determines our memories, but __40__, in that childhood, look at us.
