We stood awhile, marveling at America, both of us trying hard to feel luckier than we felt, both of us pointing out the beach pails, the shovels, the sand castles no wave would ever topple, the red and blue boats. And when we backed away, we saw our reflections superimposed, big-eyed, dressed too formally with all due respect as visitors to this country. What does this scene tell us about the speaker's feelings about America? Why do the speaker and the speaker's father not feel lucky despite their attempts to marvel at America?
