Unfamiliar big sister

This morning, when I was in the physical education class, my sixth-year-old brother, the big sister taught us to do exercises. However, there are two big sisters who rushed to teach me, and then the big sister came to teach me to wait until class. The older sister also taught, I also learned, and then the sixth grade teacher asked the big brother, the big sister who taught well, I think I still teach me, the big sister taught very well.

I want to see the big sister next time, I want to say thank you.
