From The Quotations Page
I know that you believe that you understood what you think I said, but I am not sure you realize that what you heard is not what I meant.
Robert McCloskey, State Department spokesman (attributed)
I liked this one as well:
Patriotism is your conviction that this country is superior to all other countries because you were born in it.It sorta defines, in a nut shell, how I feel about patriotism.
George Bernard Shaw
