Question

which excerpt from \the scarlet ibis\ most foreshadows that the narrator will feel regret for something he has done to doodle? but sometimes (like right now), as i sit in the cool, green - draped parlor, the grindstone begins to turn, and time with all its changes is ground away - and i remember doodle was my brother and he was going to cling to me forever, no matter what i did, so i dragged him across the burning cotton field to share with him the only beauty i knew, old woman swamp. there is within me (and with sadness i have watched it in others) a knot of cruelty borne by the stream of love, much as our blood sometimes bears the seed of our destruction, and at times i was mean to doodle. once i had succeeded in teaching doodle to walk, i began to believe in my own infallibility and i prepared a terrific development program for him, unknown to mam. daddy, of course.

Explanation:

The narrator reflects on being mean to Doodle while trying to teach him to walk, which is likely a source of regret. The mention of being mean and the development program for Doodle suggests actions that the narrator will later feel remorse for.

Answer:

The narrator was mean to Doodle while teaching him to walk.
