What made my feelings for my mother change in the depths of the alley?

(1) childhood naive "I" experience is not much, very satisfied with life, proud of my mother.

(2) when I grow up, because of vanity and comparative thinking, I think my mother's social status is low, and I begin to hate my poor home, forget my mother and be isolated from my home.

(3) Young people have more and more rich experience, more and more mature thoughts, and more and more profound and comprehensive understanding of their mothers. The old woman's words deeply touched me, educated me and made me repent.
