You can pick your friends, you can pick your nose, but you aren't allowed to pick your friends nose.
What am I not allowed to do? Nobody ever told me what I was not allowed to do, or far less explained Why I am not allowed to do it AND whether or not I had actually done whatever it is. People have just said I am not allowed to do something ("that").
You are not allowed to be vague or troll.
It must be the day for really random "questions" today on Blurtit. My advice to you is - make an account providing that you are at least 13 years old. Ask an actual question - you will get more accurate responses to what you need to know. Answer some questions here - be thoughtful in your responses - that's the best way to get some folks to "follow" you.
