An easy mistake

Yesterday in the barber's shop, while I was waiting, my father was getting his hair cut and chatting with the barber.
"My youngest has gone on holiday." he said.
"Where to?" asked the barber.
"Bosnia." said my father.
The puzzled barber looked at me.
"Borneo." I explained.

I suppose it's an easy mistake to make. Even if, only one minute before sitting in the chair, my father had asked me,
"Where's Ray gone again? Is it Bognor?"
