I suppose it was  23  for a boy's father to wear an apron? even one with race cars? 24 I never thought much of it until the last Sunday in August．As we  25   home slowly from church together, my father seemed very  26 ．"Tommy," he said letting my name roll off his   27 ．"There comes a time in every boy's 28  when he must take on responsibilities．It's time you 29 a greater role in the family．From now on, I want you to__30__the dishes on Sunday morning, so your mother and I can work the crossword puzzle（纵横字谜）together．"
