we have very strong rules about guest in Iran. first of all every body can come in our home for visit us . second, we don't have special time for guest ,but most of people ask host about their time and get appointment for visit them. In Iran almost all people have special room for their guest and family cannot use this room ,they always keep room clean and ready for their guest ,because now body doesn't know when people came to visit them. We learn this way welcome to our guest from our culture and all family knows about that. I think Canadian people doesn't have this strike rules for guest for example, they don't have special room for their guest or we are not allow to go their home without appointment.their are good with their guest if they come with appointment.
