For example, if you are talking to another researcher from a foreign university, how do you ask him or her what title would he or she be preferred to be called by?
"What's your preferred title" sounds too formal.
"What do you like to be called" sounds too informal.
"Can I call you by your first name" sounds too demanding.
"Are you comfortable with me calling you Doctor. John" sounds...awkward.
Can someone please teach me some academic etiquette?
