Could you please tell me how to answer question politely? I will have IELTS test in 4days, and I think I always be impolite when I answer questions. My English teacher said our answers like OF COURSE and ABSOLUTELY are impolite, is that true? What's more, I really want some dating sites or apps to get on with people from other countries, do you have anything recommended? Some apps I can't log in, such as Face Book and ins, because of network limitations. Thank you for your answers!!
