I’m spoken but never aloud, I hide in plain sight, wrapped in my shroud. I turn a sentence into fog, And make a man a demagogue. Break me once, and secrets bleed- What am I that spies all need?

You ask for me at the bakery, And an unlucky number you’re handed. Next time go and buy some eggs, If you don’t want this number expanded.

I hum and whir with noble intent, until your patience has been spent. I’m full of paper, yet scream for more, then jam myself with page four.

I make brits and americans disagree, but I do not make them unhappy. People often like to eat either version of me.

You can not see me when I work. If I stop working you cannot see. Keep me wet and you'll be fine. Invisible to others unless you change my color.
