While not saying that many of you are (that's not true), I am amazed that many *do* think we foreigners are idiots or at least slightly retarded :-(
And deaf. The standard response to a "Pardon me?" after some unintelligible gibberish is to repeat the same gibberish just LOUDER.
Always cracks me up. One day I will say: "Sorry Sir, I am not deaf, just a foreign retard..." with a US passport. LOL
