Okayfine - that song is called "On the Steps of a Palace." I also think some of the lines on this thread are attributed to the book writers, not Sondheim himself...
So many great choices, many listed here. My favorite image, though, is:
"I remember trees,
Bare as coat racks, spread like broken umbrellas"
As a writer, I think my favorite lyric because it speaks to me so much is:
"Stop wondering if your vision is new
Let others make that decision, they usually do,
You have to move on"
