Answer:
I am a desire to munch
I am gentle enough to soothe your skin light enough to fly in the sky and strong enough to crack rocks.
I am a protector. I sit on a bridge. One person can see right through me, while others wonder what I hide. What am I?
Glittering points that downward thrust. Sparkling spears that never rust. What am I?
You do not want me when you donβt have me but when you have me you don't want to lose me.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
