John, I replaced that handle. I make a lot of handles.
My relatives from Sweden pronounce Johnny as "yawnny".
Yep, I now answer to "John" , "Yon", "Yawn" and "Yawnny"!
My masters' students coming from Germany initially have a hard time with the informality at Swedish universities, and are not comfortable calling me "John" at first.
I keep correcting them, but at least initially, I am "Professor Herr Doktor" until they loosen up!
