     I have never taken cooking classes. I learned cooking from my mother because she was really interested

in teaching me how to cook. The main reason for this was that when my mother got married, she didn't know

how to cook anything, not even an egg. My grandmother never allowed her to stay in the kitchen when she

was cooking.

     My mother did not start to cook until she was 25 years old. In the beginning, it was very hard for her.

Therefore, she had to take cooking classes to prepare our meals. After having that experience, she decided

to teach me how to cook because she didn't want me to have the same experience.

      I remember when I was seven years old, and my mother was cooking, I was with her in the kitchen

enjoying cooking. I always helped her. Sometimes we prepared meals that my mother already knew how to

make, and sometimes we prepared them from recipes. Nowadays, I am really thankful for that experience

of people, it doesn't matter.

      I will do the same with my children because I don't want them to have the same experience as my mother.

If one day I am not with them, I want to be sure that they can carry on their lives without me.
