Read these lines from the excerpt again: I was hot, vexed, confused, yet still happy, but I hated the other boys for taking such an absorbing interest in the proceedings. I wished they were in Jericho. I felt exquisitely mean when I said cheerfully:

“This one does very well; it fits elegantly. I like a glove that fits. No, never mind, ma’am, never mind; I’ll put the other on in the street. It is warm here.”

This excerpt from the story shows that the narrator

thinks the shop girl should help the other boys
is curious about the boys’ interest in what is going on
wants to stop the boys from having fun at his expense
feels angry about the boys purchasing gloves
