What is a Thought

What is a thought?
What is a notion,
but an idea or
a strong emotion.

I know the words,
sound like a song.
I'll keep on writing,
as I move along.

Words can be pliant,
as some people you see.
Not speaking of you,
just thinking of me.

Anyone can be bent
and follow a sign,
but some become warped
becoming bigoted and blind.
