Dickie's father was shocked to see his son kick his little playmate.
"Why did you kick John?" he asked, severely.
"I am tired of playing with him. I want him to go home," was Dickie's answer.
"Then why didn't you ask him to go home?"
"Oh"—it was Dickie's turn to be shocked—"why, daddy, that wouldn't be polite!"
