During her conversation with Estevan, Taylor thinks, "This man [is] way more beyond me." What does she mean bu this, and what theme(s) in the novel thought and Taylor's subsequent thoughts help develop?

I don't think that Taylor can comprehend the pain and loss that Estevan and his wife are going through. His story about losing Ismene is "beyond tears". Taylor sees her life as "dumb luck" and blessed compared to Estevan and his wife's.
