I like drinking milk from the carton
Why do you drink from the carton?
I don't like using dishes if I don't have to.
Well, you bought the milk, so you can drink it however you want. Just make sure you tell others you drank from the carton if you live with other people.
I don't want other people to know. They will just get mad at me.
I guess that's your right, but isn't it a little gross that other people will be drinking your germs? You should tell people not to drink from it at all.
