To me, this song in the beginning is about an unwanted child and turns out that he/she screwed up their life in their oppinion and wants to be with their mother. Then goes to the birth in which the mother regrets ever getting pregnant. And the want to ride the "F-Train" the f-train is difficult to get on because it is the most used train in New York. The last paragraph is just restating the beginning that the unwanted child wants to be there for the mother like she wasn't there for him/her, then the last three verses tell what the artist thinks of a household and how it's easy to loose your idea of how to live.
