A Street Car Named Desire

Did you ever read that play?
" A Street Car Named Desire "
Its about a lady named Stella and her abusive husband Stanley. And Stella's sister Blanche comes to visit/stay with them and tensions rise when she flirts with Stanley. In that play there is this quote that I must say, even in grade 12 English stuck out to me, I never forgot it.
“there are things that happen between a man and a woman in the dark—that sort of make everything else seem—unimportant,”

I'm going to get things together.
And from the bottom there is no way to go but up.
And I'm still sleeping on the couch. But I'm starting to like it.
