I pick my nose all the time.
Is your nose bothering you?
That's a question for other people.  I dislike anybody who doesn't also pick their nose.
If you are not hurting yourself or anyone. Then there is nothing wrong with picking your nose.
But I want to pick other people's noses to show them they are missing out.
While I can appreciate your enthusiasm, this is something that you should only do in private.  Furthermore, you shouldn't judge other people for not wanting to pick their noses.  This is a choice that they have made, and it doesn't affect you.
