Answer:
Glittering points that downward thrust. Sparkling spears that never rust. What am I?
You use a knife to slice my head but you weep beside me when I am dead
People walk in and out of me. They push me and I follow. When they walk out on me I close up and I stay waiting for the next person to walk into my life when I have a more open mind
I am pinched by grandmas
I have cities with no people forests with no trees and oceans with no water.
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard. Who am I?
