And then there are the challenges of everyday language. Even a common way that Americans avoid confusion when spelling a name out loud can be confusing if you're not familiar with it. I remember a physician who had, you know, very good written English. He was used to writing papers and he could even present very well because he had presented at international conferences. But when he went to set up phone service, and he was telling them 'My last name starts with T' and they would say 'T like table?' he said 'No, I'm not a table. I don't need a table. It's T.' And he didn’t understand that they were using this strategy, this device of associating, you know, first letter of your name with a common object so that we make sure that we write a T instead of a D.
