In primary school, a music teacher took a book with children's songs from me and did not give it.

I went to her for several months almost every day, and she said that she had forgotten the book at home.

In the end, the teacher still gave it to me, and at the same time complained to my parents how obsessive I am.

After that, my mom said that if I took the debt from one of her acquaintances, I could keep the money for myself.

And I went to her all summer and as a result achieved my own.
