Grandma Erma White

I don't know who "Grandma Erma White" is, but apparently she wrote this poem, because I found it written in my dad's writing and neither of us remember where it came from:

Each night when I undress myself
Before I get in bed,
I don't feel right if I get in
Before my prayers are said.
So, I kneel beside my bed.
Yes, every single night.
I ask my Heavenly Father's help
To always choose the right.
