Why can you pick your nose and pick your friends but you can not pick your friend's nose?

Answer 1

Picking Noses (Not That Kind of Picking)Before the advent of plastic surgery, there was a time when people could not pick their noses in the same way they could pick their friends. Now, because of plastic surgery, not only can people pick their friends, they can pick their noses too! They can even pick their friends noses, right out of a catalog, if their friends are so inclined to change their nose and value a friends decision on what nose should be picked. In the past, people had a much harder time picking their noses. Peter Piper, for example, who in ages gone by, picked a peck of pickled peppers, never picked his nose, nor did he pick his friends, all poor Peter picked was a peck of pickled peppers.
