Mama, Act III
A Raisin in the Sun (1959)
Context: There is always something left to love. And if you ain't learned that, you ain't learned nothing. Have you cried for that boy today? I don't mean for yourself and for the family 'cause we lost the money. I mean for him; what he's been through and what it done to him. Child, when do you think is the time to love somebody the most; when they done good and made things easy for everybody? Well then, you ain't through learning — because that ain't the time at all. It's when he's at his lowest and can't believe in hisself 'cause the world done whipped him so. When you starts measuring somebody, measure him right child, measure him right. Make sure you done taken into account what hills and valleys he come through before he got to wherever he is.
