OK, Pasha, I will try to correct this one:

One day a Balloon got tired of being held by a thread and he decided to leave his owner. The balloon broke away from the child's hand and soared up. The wind caught him up and carried him away, and the Balloon looked down at his friends, the other balloons, which stayed there fluttering in the wind, and the Balloon began to feel proud.
"Here I am, a free balloon, and I can fly wherever I want. And you are just the slaves of your masters. Look how big I am and how much air I have, not like you. You who are comparing yourselves to me are just small fry," he said, blowing out his cheeks.
The balloon was rising higher and higher, and the higher he got, the bigger he blew up because of pride. The bigger he grew, the higher he went, until he burst with pride.
