African Proverb No Man is an Island

When an animal has an itch that needs scratching, it goes to a tree. When a human being has one, he looks for a fellow human being -Igbo Proverb
African proverb meaning is no one is self-sufficient; everyone relies on others.
”No Man Is an
Island” by John Donne
No man is an island entire of itself; every man
is a piece of the continent, a part of the main;
if a clod be washed away by the sea, Europe
is the less, as well as if a promontory were, as
well as any manner of thy friends or of thine
own were; any man's death diminishes me,
because I am involved in mankind.
And therefore never send to know for whom
the bell tolls; it tolls for thee.
