Charles summary Sometimes people fail to see the truth even when it’s right before their eyes

In the story ‘’Charles’’ there’s his parent(s) and his little sister. Charles/ Lurie wasn’t a very respectful child like when, he didn’t say goodbye to his mother on the first day of kindergarten
‘’I watched him go off the first morning with the older girl next door, seeing clearly that an era of my life was ended. My sweet- voice nursery school tot replaced by a long trousered swaggering character who forgot to stop at the corner and wave goodbye to me’’
And when he came back home, he walked in slamming the door making a raucous then he spoke impolitely to his father

‘’How was school today’’

‘’All right ‘’ he said

‘’Did you learn anything’’?

Laurie regarded his father coldly
‘’I didn’t learn anything’’

(The teacher spanked a boy for being fresh, what did he do I asked who was it Laurie thought ‘’It was Charles, he said he was fresh the teacher spanked him and made him stand in a corner he was being awfully fresh)

(What did he do I asked again but Laurie slid of his chair, took a cookie and left while his father was saying ‘’see here young man’’)
