When did Maya Angelou write Life doesn't frighten me?

shadows on the wall

noises down the hall

life doesn't frighten me at all

bad dogs barking loud

big ghosts in a cloud

Life doesn't frighten me at all.

Mean old mother gooose

lions on the loose

They don't frighten me at all

Dragons breathing flame

on my counterpane

that doesn't frighten me at all.

I go boo
