A childhood belief about classes

This happened when I was in kindergarten, and my classmates and I were in gym class. We were learning to throw a ball correctly or something like that. My partner and I were across from each other, and the teacher kept saying to throw with whatever hand you write with. I was right handed, and the other girl was right handed, but it would look like she was throwing with her left. I would be like, "No, you're supposed to throw with your right hand!" and she'd be like "I AM throwing with my right hand!" I also had this problem figuring out with side of my chest to put my hand on during the pledge of alligence.
