You talk to your lawyer to see if you have legal recourse. The lawyer says that librarians are entitled to remove patrons have offensive behaviour which includes flatulence. You are argue with your lawyer telling him that it wasn't even you who farted. The lawyer says jokingly 'Maybe you should take some air samples from the library quickly so that you can prove that the fart wasn't your's. You realise that your lawyer thinks your predicament is amusing and suggests that you go to doctor, get some charcoal tablets and tell the librarian that you are doing something about the flatuelence problem.

What do you do?

Agree with the laywer and go to the doctors
