I'm going to piss off my grandma by telling her I want to emigrate to Canada
What makes you want to piss off your grandmother?
When I told her about my plans she started to cry and asked me not to go. I want her to be upset.
You shouldn't say mean things to your grandparents. She was obviously upset. It's wrong to get off o  her pain.
I just want to show her that she needs to let me do whatever I want or stay out of my life.
Knowing that you're going to make your own Grandmother cry and being proud of that fact is pretty messed up. You wouldn't like it if someone said things to you that hurt your feelings on purpose, so why do it to a family member that you're meant to care for?
