I want to ruin tomorrows breakfast somehow
Why would you want to do something so terrible to ruin breakfast?
I want to do something terrible
It's really rude to try to ruin someone's breakfast for your own amusement. You should be respectful to people. If you go around ruining people's meals then no one will want to interact with you.
I don't see anything wrong here. I also want to disrespect people and ruin their meals.
Disrespecting people and ruining their meal is wrong. It sounds you need to really think about what you are doing and how you'd feel if someone ruined your breakfast. This self destructive behavior will put you on a path towards ruin.
