What do you think about me telling our teacher that my classmate's mother passed away?
What would make you want to tell your teacher about your classmate's mother?
For me it's fun to see the pain on his face when he hears about someone else's misfortune.
Telling your classmate's personal business to your teacher just to make him feel bad isn't right. If your classmate wants to share that with the teacher then that's their decision. It isn't your decision to make.
Yeah yeah, but I already told the teacher about the kid and she's concerned. She can't do anything about it anyway.
It wasn't right of you to tell your teacher, especially if you knew it would make them upset. You shouldn't try to upset others for your own pleasure. I think you should talk to someone about why you feel this way.
