my guest this week, sonia mazano. for decades she played "maria" on sesame street. >> sonia mazano, you write at several junctures in the book about being a sort of almost racial go between. "if i wore my hair this way, people would think i was black. if i wore it another way, they'd think i was--" and it was almost a question mark there, because even you didn't know what to put in there. >> i know. it was a very ambiguous time racially because the puerto- my family, we all considered ourselves white. even though... all puerto ricans were white in their mind. and even though we had neighbors that were black as night and they were puerto rican. and there was always sort of don't the admonishment-- "please don't stay out in the sun too long because you are getting dark". and my sister, who's eight years older, would say to me, "look, everybody who comes into a society checks out who's the lowest on the totem pole and then tries not to be lower than that". and that's where all of this racial ambiguity is coming from. and
