I end in silence, but am known to be loud. Please don't yell my name in a crowd.

Once spoken, instantly broken. What am I?

Born through terror, a sacrifice made, I mirror the form from which I was laid. Strike me once, and two shall bleed, but only one survives the deed.

I march without legs and split crowds without lines. I crown no one, yet hearts obey me. I hide in sands and in drums, in code and in headaches, in the pull of the moon and the turning of days.What am I?

When you need me, you throw me away When you're done with me, I come back to you
