OMG!
This actually shows the problem of our education:
1. The teacher does no teaching, just blaming, insulting and labeling. He does not give any constructive feedback throughout.
2. The student actually did not write anything hurtful to others. He or she just wrote something "outside the box" in my opinions.
3. The teacher requests a re-do but without reasoning. Re-do for what and why?
4. The student may be too young to understand the feeling of lossing a father. May be he is a bit naughty to write some funny things like this. This is the best chance for the teacher to do something great - to let the student udnerstand it is a plainful thing to lose one's love and he or she needs to show comforts to others.
No wonder our education is so ineffective.
