Do you learn from your mistakes? I hope so. But have you ever made the same mistake twice

Do you learn from your mistakes? I hope so. But have you ever made the same mistake twice? I have. Sometimes I make the same mistake three or four times!
Sometimes, good things happen because of mistakes. Once I got on the wrong train. That was a big mistake. But on that train, I saw a good friend. I was so happy I made that mistake!
Another time I ruined a surprise. My mother planned a surprise party for my father. She told me it was a secret. But I was just a little boy and I couldn’t keep the secret. I told my father about the party. At first, my mother was mad at me. But then my father said he was happy he knew about it. He said he didn’t like surprise.
When a good thing comes out of a mistake, that’s a happy accident.
