Shyness is a fear. Introversion isn't.
The confusion arises because shyness and introversion both often result in quietness. Therefore, introverts can appear shy even when they aren't.
O.K so you know more than the "New Oxford American Dictionary"?
If you knew anything about psychology you would know that scientific definitions are often different to lay-people's definitions. Even psychologists don't agree on what introversion means. Its the same for many other sciences.
To me it sounds like someone is an introvert and desperately wants Federer to be one too (i can relate to that).
