Nick Adams Timeline and Summary

Nick's dad takes him along to an Indian camp to play intern to a particularly difficult childbirth.
Nick's father explains the mechanics of childbirth to him in a very stern fatherly way. But Nick is more concerned with the woman's screams of pain.
Nick looks away while his father does stomach-turning things like operating on the woman and then stitching her up. Remember: no anesthesia. Yikes.
When the husband's suicide is discovered, Nick sees every gory bit of it before his father can hide it from him.
On the boat ride back, Nick's father apologizes to Nick for bringing him along, and Nick (who is now understandably worried about what he just saw) asks questions about suicide and dying.
At the end of the story Nick feels certain that he will never die.
