Georgie felt that Sam would WANT him to come and play in the shack if Penrod didn't make Sam do everything HE wants.

What hurt Georgie most is that it's SAM'S shack, and he felt for another boy to come and tell him that he mustn't even go NEAR it--well, of course, it was very trying.

And he's very much hurt with little Maurice Levy, too.
He said that he was sure that even Penrod would be glad to have him for a member of their little club if it weren't for Maurice--and I think he spoke of Roddy Bitts, too." The fact that the two remaining members were coloured was omitted from this discourse which leads to the deduction that Georgie had not mentioned it.
"Georgie said all the other boys liked him very much," Mrs.Bassett continued, "and that he felt it his duty to join the club, because most of them were so anxious to have him, and he is sure he would have a good influence over them.

He really did speak of it in quite a touching way, Mrs.Williams.Of course, we mothers mustn't brag of our sons too much, but Georgie REALLY isn't like other boys.

He is so sensitive, you can't think how this little affair has hurt him, and I felt that it might even make him ill.
