Помогите точно перевести текст.

The next morning, the Widow Douglas was very angry at me because of my dirty clothes. So I decided to be good.
I went out with the Tom Sawyer Gang for about a month, but we never robbed anybody and we never killed anybody. We only played. After a time I stopped going to the meetings.The other boys stopped going, too.
Three or four months went past and it was winter time. The Widow sent me to school every day. I could spell and read and write a little . They wanted to teach me numbers, but I didn't like them and I didn't learn very much.
At first I hated school, but after that it Ok. When i got really bored with it, i didn't go . The teacher hit me the next day , but i didn't mind. Soon i even liked living with the Widow. Something I still slept in the woods, but most of the time i liked sleeping in a bed.
I didn't know where Pap was. Pap's my dad. He came to town sometimes. I always hid in the woods when he came to town. One day, I heard that he was dead. But you could never be sure about Pap.
One morning, I was going to school. When I saw some footprints in the snow in front of the house, i looked closely at them. There was a small cross on the left foot. That was Pap's shoe! The cross was there because it kept away bad luck.

I thought, "If Pap's here, I'm in trouble. He probably wants my gold."
So i ran to the Judge's house.
"Do you still have my $6,000 of gold?" I asked.
"I do," he answered. "Do you want it ?"
"No, sir!" I said. " I don't want it! I want you to have it. I want to give it to you!".
The Judge looked surprised. I said, " Don't ask me any questions about it. You just keep the gold."
He thought about this for a minute. He didn't know Pap was in town. But he was a smart man and he understood. " I'll buy your gold from you," he said. "I'll give you one dollar for it."
I agreed, and signed a piece of paper. He gave me my dollar and I left. That night, I went to bed early. When I opened my bedroom door, there was Pap! He was sitting on my bed.
