I'm going to eat all the cheese in the break room
Is there a reason you want to eat every bit of cheese in the break room?
Because I love cheese and I can.
It is not good to be greedy and take the last of the cheese. It was meant to be shared by everyone.
So what? No one here really likes cheese, so it should be fine.
Even though you might think no one else wants any of the cheese, you shouldn't eat it all because that's greedy and people might see you as selfish and disrespectful. I understand you like cheese, as I do too, but take an appropriate portion in order to avoid causing any resentment issues.
