I'm thinking of asking my little sister to walk through the burning coals slowly.
Why would you consider harming your sister by making her walk on burning coal?
She stole the show and she was too loud for everyone! So she should be the main event.
It's a pretty sadistic form of punishment. It's wrong to want to punish her this way because it's too dangerous. If your parents find out this is how you treat your sister, I am sure they will make you walk on burning coal as well.
If she wants attention so much whats so wrong with making her do something that will gain even more attention?
Walking on hot coals should be left to the professionals. You could burn her and she might even lose her legs or feet. You can tell her how angry you are about her stealing the show after everyone goes home.
