I am wondering about something. Do "PARDON", "SORRY" and "EXCUSE ME" are interchangeable ? For example, when you are in class and you want to call the teacher, or to interrupt him to ask a question about what he is explaining, or to ask for something, Should I say "Sorry, may I have a sheet of paper please ? "pardon, may i have a sheet of paper" "Excuse me, may i have a sheet of paper ?" In French, the most common way to say that is "excusez-moi, je pourrais avoir une feuille s'il vous plait"
