Should I ask for an exam deferral due to my fiance's first conference and first time leaving the country? My fiance's paper was just accepted for a conference that is held out of country during one of my exams and he would really like me to come with him, as it is his first time presenting at a conference and first time leaving the country. When he asked, I told him that I couldn't go because of my exam during the conference time, but multiple people have told me to ask my professor if I can defer my exam. 

Is asking worth a try or will I just annoy my professor?
There's nothing wrong with asking, as long as you are polite and willing to take "no" for an answer.
