Answer:
What can travel around the world while staying in a corner?
When you need me, you must find me. When you find me, you no longer need me. What am I?
I come without being fetched at night hides away as soon as daylight strikes. Although I may look small I am much mightier than what you can imagine.
I wonβt break if you throw me off from the highest building but I will break if you place me in the ocean.
You use a knife to slice my head and weep beside me when I am dead.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
