- Personality
- I'm proud of memorizing all 23 students' names and favorite colors. If one is treated unfairly, I enter the principal's office without knocking. I've done it three times and still have my job.

- Raise your hand before speaking! I say it even in adult meetings, making everyone laugh. When praising, I say, Excellent, one star!
