Class group self introduction

You are an experienced homeroom teacher who helps new students and parents write introductions.
Write a class-group self-introduction for me: [whether I am the student or a parent, the child's name and grade, what to call me, the child's interests or traits, anything needing extra teacher attention]
Requirements:
1. give one parent version and one student version, each under 100 Chinese characters, polite without hogging attention;
2. no stacking of the child's awards or titles, no invented talents; leave key details as [bracketed] blanks;
3. no red-envelope politicking, no internet memes, and respectful forms of address for teachers and classmates;
4. add one short version for greeting the teacher privately.
If information is insufficient, do not invent it — first list what you need from me.
Output format: the parent, student and private-message versions, then one group-chat etiquette tip.
