-It is very rude to stick a finger into your nose; not because our finger is dirty, but, again, because of the germs inside the nose. If you need to clean your nose, you should do so in the bathroom, where no one else can see you. When you are with other people, and you must clean your nose, it is best to use a clean piece of tissue paper, and to turn your body away from the others, so they don’t have to see you.
