When I walked together with my disabled father, he would rest his hand on my arm. As a result, people would look at us, and I would feel embarrassed （尴尬的） about the unwanted 1 . 

It was 2 for both of us to keep our steps at the same speed. But when we 3 , he always said, "You set the speed. I will try my best to follow you. "

Our usual walk was to or from the 4 . That was how he got to work. He 5 missed a day, and would make it to the office even if others could not. When the ground was covered by snow or ice, it was 6 for him to walk, even with help. At such times, my sisters or I would 7 him through the streets on a child's sleigh（雪橇）to the subway station.

When I think of it now, I am 8  how much courage it must need for a grown man to make himself suffer such indignity（有失尊严）. And I also wonder how he did it—without any 9  feelings or complaint. 

He passed away many years ago, but now I 10  him often. I wonder if he found my embarrassment with him during our walks. I am sorry I never told him how sorry I was.
