Thank you!
My student wants to be called Jasko. This may be a normal pet form in Bosnia, but I'm sure he finds it even more important to go by Jasko while he's in the USA. I actually discovered that the registrar at my university had him listed as female; evidently someone in the registrar's office couldn't believe that there really would be a man named
Jasmin when they were entering his records into the computer and so wrongly "corrected" his sex to female. :)
