As my official bio reads, I wes made in Cuba, assembled in Spain, and imported to the United States — meaning my mother, seven months pregnant, and the rest of my family arrived as exiles from Cuba to Madrid, where I was born. Less than two months later, we emigrated once more and settled in New York City, then eventually in Miami, where I was raised and educated. Although technically we lived in the United States, the Cuban community was culturally insular in Miami during the 1970s, bonded together by the trauma of exile. Wat's more, it seemed that practically everyone was Cuban: my teachers, my classmates, the mechanic, the bus driver. I didn't grow up feeling different or treated as a minority. The few kids who got picked on in my grade school were the ones with freckles and funny last names like Dawson and O'Neil.

Finally, Aisha finished with her customer and asked what colour Ifemelu wanted for her hair attachments.

"Colour four."

"Not good colour," Aisha said promptly.

"That's what I use."

"It look dirty. You don't want colour one?"

"Colour one is too black, it looks fake," Ifemelu said, loosening her headwrap. “Sometimes I use colour two, but colour four is closest to my natural colour."

[...]

She touched Ifemelu’s hair. "Why you don’t have relaxer?"

"I like my hair the way God made it."

"But how you comb it? Hard to comb." Aisha said.

Ifemelu had brought her own comb. She gently combed her hair, dense, soft and tightly coiled, until it framed her head like a halo. “It's not hard to comb if you moisturize it properly," she said, slipping into the coaxing tone of the proselytizer that she used whenever she was trying to convince other black women about the merits of wearing their hair natural. Aisha snorted; she clearly could not understand why anybody would choose to suffer through combing natural hair, instead of simply relaxing it. She sectioned out Ifemelu's hair, plucked a little attachment from the pile on the table and began deftly to twist.

A Minor Bird

I have wished a bird would fly away,
And not sing by my house all day;

Have clapped my hands at him from the door
When it seemed as if I could bear no more.
The fault must partly have been in me.
The bird was not to blame for his key.

And of course there must be something wrong
In wanting to silence any song.

No poema de Robert Frost, as palavras "fault" e "blame" revelam por parte do eu lírico uma

Algumas toneladas de medicamentos para uso humano e veterinário são produzidas por ano. Os fármacos são desenvolvidos para serem estáveis, mantendo suas propriedades químicas de forma a atender a um propósito terapêutico. Após o consumo de fármacos, parte de sua dosagem é excretada de forma inalterada, persistindo no meio ambiente. Em todo o mundo, antibióticos, hormônios, anestésicos, anti-inflamatórios, entre outros, são detectados em concentrações preocupantes no esgoto doméstico, em águas superficiais e de subsolo. Dessa forma, a ocorrência de fármacos residuais no meio ambiente pode apresentar efeitos adversos em organismos aquáticos e terrestres.
