War is a form of really bad manners, in a strange way. Invading a country I think is just the worst possible manners. 'You're not invited!' Gate crashing on a large scale!

I didn't like the Feds coming to town when I was in Miami, telling me what to do. I didn't like them coming to town and thinking that they knew more about Miami than I do.
Going to a party uninvited always has been a negative action. It never has been acceptable. At the very least, it upsets kitchen preparations, parking arrangements, and even details such as space for hanging coats and depositing dripping umbrellas.
