Any kind of 3 ride seemed to give him pleasure. 4 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 5 the water, moving through it, having it all around me. I was not a strong 6 , or one who learned to swim early, for I had my 7 . But I loved being in the swimming pool close to my father’s office and 8 those summer days with my father, who 9 come by on a break. I needed him to see what I could do.
