when it's my time to call your bluff I'll call you beautiful and leave it alone

What is the most devastating line
from a musical of all time
and why is it
“I think there’s a time
to come to New York
and a time to leave.”?

I went from a Central Florida mallrat
to a South Florida Target possum,
with a lifetime in between,
and those are the years
I am most famous for.

Counting on you alone
to rip your guts out,
I am not Isaac Bashevis,
so I can’t sing you in Yiddish
how to live your life,
but I will find my freedom
and help you find yours.
