The U.S. Postal Service takes a lot of hits it doesn’t deserve, but its Maya Angelou fiasco is just gift-wrapped for critics.
 
Honoring Angelou with a  commemorative stamp unveiled Tuesday was a lovely idea. Erroneously quoting a different writer on the stamp was an embarrassment.  Refusing to correct the mistake is just plain silly.
 
Some things you just have to get right.
 
Angelou is one of the world’s most beloved writers. Before her death last year, she had published a seven-book autobiography — including the best-known installment, “I Know Why the Caged Bird Sings” — as well as 18 collections of poetry, numerous plays, essays, teleplays and even a couple of cookbooks.
 
Postal Service officials should pick a quote, any  quote, from that wealth of material.  If you’re going to honor a writer, at least use her own words.
 
The words on the stamp, “A bird doesn’t sing because it has an answer, it sings because it has a song,” were written by Joan Walsh Anglund in her children’s book “A Cup of Sun.”
 
Angelou frequently cited the quotation in interviews. President Barack Obama attributed it to her in 2013. Humans err.
But shame on postal officials for refusing to make it right.
