i actually thinks that it's about the whole empty nest syndrome,
like in the first line it mentions 17 years
most kids are 17 or 18 when they graduate high school
and go off to college
so she's letting him go
driving him to his school
somewhere along the east coast
and then she relives the steps of his life
from his birth to the current drive
in the last stanza i picture her driving away from the college
tearing up and thinking about how he's not her baby anymore
