Quote from Sophia in Foreign Exchange
Blanche: Dorothy, what'd they say about the blood test?
Dorothy: Oh, we didn't wait around for the results. I don't need a blood test to tell me who my mother is. A mother is someone who raises you and loves you and is always there for you. I don't need any more proof than that.
Sophia: Me neither. I raised her, and I was the one who got her through that awkward period. The 50 toughest years of my life.
