How does the author show that Big Ma is an optimist or someone who looks on the bright side of things?

Big Ma shows her love and optimism through love and support..... family first.

Big Ma was not one for coddling any of us, but now she turned from the stove and, wiping her hands on her long white apron, sat down on the bench and put her arm around Little Man. “Now, look here, baby, it ain’t the end of the world. Lord, child, don’t you know one day the sun’ll shine again and you won’t get muddy no more?”

“So ain’t no use frettin’ ’bout it. One day you’ll have a plenty of clothes and maybe even a car of yo’ own to ride ’round in, so don’t you pay no mind to them ignorant white folks. You jus’ keep on studyin’ and get yo’self a good education and you’ll be all right.
