My friend just opened a fresh packet of cigarettes, so I'm thinking of nicking them and them and throwing them in the bin.
I don't get it. Why would you want to throw your friend's cigarettes away?
I don't like it when he smokes because they smell terrible.
You have no right to take something that does not belong to you and dispose of it. You are stealing your friend's property and you need to be more respectful of what belongs to someone else.
Yeah, but they're bad for his health, too.
I agree that they're not good for his health, but you still shouldn't take them and throw them in the trash. He's not going to stop just because of that.
