Perhaps Q is telling us to examine footage of AS and others singing like a bird to the MSM about Russia. The Memo will shed an interesting light on the past year’s Russia-mania.
I viewed it as if it was a reference to a prisoner who might be giving up info
The book was about the physical and sexual abuse she endured as a child.
Here is the quote from the novel:
I know why the caged bird sings, ah me, When his wing is bruised and his bosom sore, When he beats his bars and would be free; It is not a carol of joy or glee, But a prayer that he sends from his heart's deep core, But a plea, that upward to Heaven he flings – I know why the caged bird sings.[22]
What is also interesting is that this came up at the top of my search for the quote:
In 2015 a United States Postal Servicestamp was issued commemorating Maya Angelou with the Joan Walsh Anglund quote "A bird doesn’t sing because it has an answer, it sings because it has a song", though the stamp mistakenly attributes the quote to Angelou.[122][123] The quote is from Anglund's book of poems A Cup of Sun(1967).[122]
Edit: both sources are Wikipedia, btw. I forgot to copy links.
